8of Paulina's suitcase. How many pounds does Rebecca's suitcase weigh?

Answers

Answer:

4 pounds

Step-by-step explanation:

Paulina has a suitcase full of clothes that weighs 4 4/7pounds. Rebecca has a suitcase full of clothes that weighs

7/8 of Paulina's suitcase. How many pounds does Rebecca's suitcase weigh?

Weight of Paulina's suitcase = 4 4/7 pounds = 32/7 pounds

Weight of Rebecca's suitcase = 7/8 of Paulina's suitcase

Hence, the weight of Rebecca's suitcase in pounds = 7/8 of 32/7 pounds

= 7/8 × 32/7

= 4 pounds

Therefore, Rebecca's suitcase weighs 4 pounds.

A researcher posed a null hypothesis that there was no significant difference between boys and girls on a standard memory test. He randomly sampled 40 girls and 40 boys in a community and gave them the standard memory test. The mean score for girls was 68 and the standard deviation of mean was 5.0. The mean score for boys was 66 and the standard deviation of mean was 5.0. What is the p-value and your conclusion at alpha

Answers

Complete Question

Answer:

The p-value is [tex]p-value =0.073614[/tex]

The conclusion is

There is sufficient evidence to support the claim that there was no significant difference between boys and girls on a standard memory test

Step-by-step explanation:

From the question we are told that

The sample size of boys and girls is [tex]n_1= n_2 = n = 40[/tex]

The standard deviation is [tex]s_1= s_2 = s = 5[/tex]

The level of significance is [tex]\alpha = 0.05[/tex]

The sample mean for boys is [tex]\= x_1 =66[/tex]

The null hypothesis is [tex]H_o : \mu_1 = \mu_2[/tex]

The alternative hypothesis is [tex]H_a : \mu_1 < \mu_2[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\= x_1 - \= x_2 }{ \sqrt{\frac{s_1 ^2 }{n_1} + \frac{s_2 ^2 }{n_1} } }[/tex]

=> [tex]z = \frac{66 -68 }{ \sqrt{\frac{5^2 }{40} + \frac{5 ^2 }{40} } }[/tex]

=> [tex]z = -1.789[/tex]

From the z table the area under the normal curve to the left corresponding to -1,789 is

[tex]P(Z < -.1789 ) = 0.036807[/tex]

Generally the p-value is mathematically represented as

[tex]p-value = 2 P(Z < -.1789 )[/tex]

=> [tex]p-value = 2 * 0.036807[/tex]

=> [tex]p-value =0.073614[/tex]

From the values obtained we see that [tex]p-value < \alpha[/tex] hence

The decision rule is

Fail to reject the null hypothesis

The conclusion is

There is sufficient evidence to support the claim that there was no significant difference between boys and girls on a standard memory test

A department store buys200 shirts at a cost of $ 5400 and sells them at a selling price of $30 each. Find the percent markup

Answers

200 shirts x $30 = $6000

Total sales would be $6000

Profit = 6000 - 5400 = $600

Divide profit by cost:

600/5400 = 0.1111

Multiply by 100 for percentage:

0.111 x 100 = 11.1%

Rounding to nearest percent would be 11% markup

Answer:

b) Probability of selecting one biography and then one mystery, without replacement: approximately 0.0556 or 5.56%.

The probability of each situation can be calculated as follows:

a) Selecting one biography and then one mystery, with replacement:

With replacement means that after each selection, the book is put back on the shelf before the next selection.

The probability of selecting the biography first is 1 out of 10 books (since there is 1 biography out of 10 books).

The probability of selecting the mystery book next is 5 out of 10 books (since there are 5 mysteries out of 10 books).

The overall probability is the product of the individual probabilities:

Probability = (1/10) * (5/10) = 1/20

So, the probability of selecting one biography and then one mystery, with replacement, is 1/20.

b) Selecting one biography and then one mystery, without replacement:

Without replacement means that after each selection, the book is not put back on the shelf before the next selection.

The probability of selecting the biography first is still 1 out of 10 books.

However, after selecting the biography, there are now 9 books left on the shelf, and the probability of selecting a mystery is 5 out of 9 books (since there are 5 mysteries out of the remaining 9 books).

The overall probability is the product of the individual probabilities:

Probability = (1/10) * (5/9) ≈ 0.0556 or 5.56%

So, the probability of selecting one biography and then one mystery, without replacement, is approximately 0.0556 or 5.56%.
