What equations and statements should be used for this problem? Do I select any hypothesis I want? How do I phrase the hypothesis and write the equations? If I have data, what makes the hypothesis true or false?

1) Conduct hypothesis test by comparing monthly average between the two year

2) Within each year, run a appropriate hypothesis comparing June and August.

Answer #1

Solution1:

Let us assume that you have data for sales

Null hypothesis :

The true avearge sales for two years are equal .let us assume 2017 and 2018

Alternative Hypothesis:

choose level of significance as 0.05 that is alpha=0.05

Conduct t test for difference in means.

Obtain t statistic and p value .

decsion rule is

if p<0.05 reject Ho

if p>0.05 Do not reject H0

basing on this we can accept or reject claim

Solution2:

For this comapre monthly sales

ex

H0:

H1:

choose level of significance as 0.05 that is alpha=0.05

Conduct t test for difference in means.

Obtain t statistic and p value .

decsion rule is

if p<0.05 reject Ho

if p>0.05 Do not reject H0

basing on this we can support or reject the claim

Our friend the waffle-man is back and wants to do more hypothesis tests for proportions, but this time for four waffle recipes. He randomly selected 250 waffle consumers and found that 100 (40%) of the 250 preferred Waffle No. 2. He conducted a hypothesis test with H0:p=0.25H0:p=0.25, Ha:p>0.25Ha:p>0.25. Notice the proportion under the null distribution is p_0 = 0.25. The test statistic for this problem is 5.47. You can verify for yourself that the probability of observing this test statistic...
