A researcher is interested in consumer preferences among three brands of yogurt. A sample of 90 people is obtained,
and each individual is asked to taste each brand and then select his/her favorite. The resulting frequency data are as
follows:
Brand A
Brand B Brand C
37
21
32
Do the data indicate any significant preferences among the three brands? Test at the .05 level of significance.
State the null hypothesis (1 point), the expected frequency for each category (3 points), the value of chi-
square (4 points), the df (1 points), the critical value of chi-square (2 points), and the decision regarding
significance (1 points).
Answer:
Step-by-step explanation:
From the given information:
The null hypothesis: all three brands are equally likely to their expected value
The alternative hypothesis: preferences exist among the three brands i.e. at least one is different from the expected value.
The expected frequency = [tex]f_e[/tex]
The observed frequency = [tex]f_o[/tex]
[tex]f_e[/tex] [tex]f_o[/tex] [tex](f_o- f_e)^2[/tex] [tex]\dfrac{(f_o - f_e)^2}{f_e}[/tex]
37 30 49.00 1.633
21 30 81.00 2.700
32 30 4.00 0.133
[tex]X^2 = \sum\dfrac{(f_o-f_e)^2}{f_e} = 4.47[/tex]
Degree of freedom = [tex](n-1)[/tex]
= 3 -1
= 2
At ∝ = 0.05 and df = 2
The critical value [tex]X^2_{0.05, 2}= 5.99[/tex]
Decision rule:
Since the calculated chi-square is less than the critical value, we do not reject the null hypothesis.
Thus, the null is retained with a calculated chi-square value of 4.47 and a critical chi-square value of 5.99.

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
bottles of 25% Albumin in stock. How many bottles should the pharmacy
technician prepare to provide the required dose?
Answer : The number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.
Step-by-step explanation :
As we are given that a patient needs a total dose of 50 grams of albumin and the pharmacy has 50 mL bottles of 25% Albumin in stock.
Now we have to determine the number of bottles should the pharmacy technician prepare to provide the required dose.
As,
The pharmacy has stock albumin = [tex]50mL\times \frac{25}{100}[/tex]
The pharmacy has stock albumin = 12.5 mL
So,
Number of bottles should the pharmacy technician prepare to provide the required dose = [tex]\frac{50}{12.5}[/tex]
Number of bottles should the pharmacy technician prepare to provide the required dose = 4
Therefore, the number of bottles should the pharmacy technician prepare to provide the required dose are 4 bottles.

Write the slope intercept form of the equation of the line through the given points
Answer:
9) y = -3x - 4
10) y = -1/3x + 14/3
11) y = x - 1
12) y = -7/5x - 18/5
13) y = 3/5x + 9/5
14) y = -2x - 3
Step-by-step explanation:
For this explanation, let's use the last problem as the example. You would use the formula y=mx+b. The first thing you would need to find would be the slope, or m. So, you would find the slope and conclude the answer is -2. After that, you would solve for b and get the answer. Hope this helped!

Consider the following problem: There are 722 identical plastic chips numbered 1 through 722 in a box. What is the probability of reaching into the box and randomly drawing the chip numbered 552
Answer:
Probability of reaching Chip number 552 = 1 / 722
Step-by-step explanation:
Given:
Total number of chips = 722
Chip number selected = 552
Computation:
Probability of reaching Chip number 552 = Number of chip selected / Total number of chips
Probability of reaching Chip number 552 = 1 / 722

Identify the constant of Proportionality Write an equation to relate weight, w, to the price, p.
Answer:
m = .45
p = .45w
______
.45 = 9/20
Explanation:
m is the rate of change equal to the price over the weight or p/w.
Because this relationship is proportional, each weight divided by its corresponding price must equal the same fraction because it is constant.
We can prove this by dividing each price by its weight to find this proportion.
1.35/3 = 2.7/6 = 27/60 = 9/20 = 0.45
1.71/3.8 = 171/380 = 9/20 = 0.45
2.34/5.2 = 234/520 = 117/260 = 9/20 = 0.45.
Since equal the same value, this means that 9/20 or .45 is our proportion.
in terms of p = mw
p/w = 9/20.
p = mw → p/w = m → m = p/w = .45 .
Thus, p = .45w,
so m = .45.
Which means that for every .45 or 9/20 w or weight, there is a price of $1.
3 Drag the tiles to the boxes to form correct pairs. Match the expressions with the property used to generate 5y + 2y+ 6+2. Distributive Property 6y - y + 2y + 10 - 4 + 2 5y + 2(y + 3) + 2 combining like terms 5y + 2 + 6 + 2y Commutative Property € cared
Answer:
Distributive Property = 5y+2(y+3)+2
combining like terms = 5y+2+6+2y
Commutative Property = 6y-y+2y+10-4+2
Step-by-step explanation:
The correct matching of the properties will be:
Distributive Property = 5y+2(y+3)+2
combining like terms = 5y+2+6+2y
Commutative Property = 6y-y+2y+10-4+2
Original expression: 5y + 2(y + 3) + 2
How to match the valueApply the distributive property by multiplying 2 to the terms inside the parentheses:
5y + 2y + 6 + 2
Combine like terms:
(5y + 2y) + (6 + 2)
7y + 8
Rearrange the terms using the commutative property:
(7y + 2y) + (6 + 2)
9y + 8 + 8
Simplifying further, we have:
9y + 16
Therefore, the simplified expression is 9y + 16.

Find the values of the variables in the parallelogram.
Step-by-step explanation:
We can find x very easily because the left and right sides are parallel,making the diagonal connecting them a transversal therefore x=33°
To find y we know that the sum of interior angles of a triangle is 180°
y+109°+33°=180°
y+142°=180°
y=38°
Now,
x+38°+z=180
33+38+z=180
z=180-71=109°

A party rental company has chairs and tables for rent. The total cost to rent 4 chairs and 8 tables is 89 . The total cost to rent 2 chairs and 3 tables is 34 . What is the cost to rent each chair and each table?
Answer:
Let C = cost to rent each chairLet T = cost to rent each table 4C + 8T = 732C + 3T = 28 Multiply the 2nd equation by (-2) and then add the equations together 4C + 8T = 73-4C - 6T = -56 2T = 17T = 17/2 = 8.5 Plug this in to the 1st equation to solve for C 4C + 8(17/2) = 734C + 68 = 734C = 5C = 5/4 = 1.25 So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50
