The primary concern for performing a hypothesis test to compare the means, mu1 and mu2, of two populations is deciding whether the mean of population 1 differs from the mean of population 2. a. determine the null and alternative hypotheses. note: always place the mean of population 1 on the left. b. classify the hypothesis test as two-tailed, left-tailed, or right-tailed.

The null and alternative hypothesis are designed below. We use Two-tailed t-test to perform this hypothesis.  

Step-by-step explanation:

We are given the following information in the question:

The two tailed-sample t-test is used to determine if two population means are equal and helps us to compare the means.

a) The null and the alternate hypothesis  can be designed as

The null hypothesis states that the mean of population 1 is equal to the mean of population 2.

The alternative hypothesis states that mean of population 1 is not equal to the mean of population 2.

b) We use Two-tailed t-test to perform this hypothesis.

answer: i don't understand. what are the options

step-by-step explanation:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
