Assuming all model requirements for conducting the appropriate procedure have beenâ€‹ satisfied, is the mean IQ of the students in theâ€‹ professor's statistics class higher than that of the generalâ€‹ population, 100? Explain what statistical procedure should be used for this research objective.

Answers

Answer 1

Answer:

Step-by-step explanation:

The right statistical procedure is by applying a hypothesis test that uses a single mean. Here, if we are to talk about comparison, it should be between the mean IQ of the students in the class and the national average IQ. The class is not for a comparison between two population means because it is viewed as the sample of the population. That is to say, the required task is to determine if the sample mean is greater than the population mean. We can conclude that this obeys a hypothesis test rather than a confidence interval.

Population of California in the year 1995 was 32 million. If the population grows at a rate of 2%, what will the population be in 2025?

Answers

Answer:

hi 51.2 is the answer

Step-by-step explanation:have a good day.

The population of California in the year 2025 is approximately 57.96 million.

To calculate the population of California in 2025, we need to use the population growth formula:

Population in the future = Population in the present * [tex](1 + Growth rate)^{Number of years}[/tex]

Given:

Population in 1995 = 32 million

Growth rate = 2% = 0.02 (in decimal form)

Number of years = 2025 - 1995 = 30 years

Now, let's calculate the population in 2025:

Population in 2025 = 32 million * (1 + 0.02)³⁰

Population in 2025 ≈ 32 million * (1.02)³⁰

Population in 2025 ≈ 32 million * 1.8114

Population in 2025 ≈ 57.9648 million

Therefore, the population of California in the year 2025 is approximately 57.96 million.

Answer:6.26Hope this helps!!

Answer:

6.26

Step-by-step explanation:

Integer Part: 6

Fractional Part: 258

If the last digit in the fractional part of 6.258 is less than 5, then simply remove the last the digit of the fractional part.

If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.

If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.

If the last digit in the fractional part of 6.258 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.

Alaina is making a birdseed mix with 2 1/3 lb sunflower seeds, 5/6 lb cracked corn, and 1/6 lb peanuts. How much cracked corn does Alaina need to make 5 lb of birdseed mix? Show your work.

Answers

Answer:1.25

Step-by-step explanation:

If you add everything it makes 3 and 1/3 pounds you want 5

If you divide 5 by 3 and 1/3 it's 1.5

Then you just need to multiply 5/6 by 1.5

For making 5 lb birdseed mix 1 ¹/₄ lb cracked corn will be used.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

Alaina is making a birdseed mix with 2 1/3 lb sunflower seeds, 5/6 lb cracked corn, and 1/6 lb peanuts.

adding everything to make birdseed mix = 2 1/3 + 5/6 + 1/6 =10/3 lb

Now,

for making 10/3 lb birdseed mix = 5/6 lb cracked corn is used

in other words :

for making 1 lb birdseed mix = (5/6) x (3/10) lb cracked corn is used

that is , for making 5 lb birdseed mix = (5/6) x (3/10) x 5 lb cracked corn will be used.

= 15/12 = 5/4 = 1 ¹/₄ lb cracked corn will be used.

Therefore, for making 5 lb birdseed mix 1 ¹/₄ lb cracked corn will be used.
