Answer:

Step-by-step explanation:
We have find the hypothesis that helps us o determine the nature of test.
- There are three types of test two tailed test, lest tailed test or right tailed test
- It is the alternative hypothesis that states the nature of test.
- The null hypothesis always state that the sample belongs to the population and always shows equality to the population.

Answer:17.3964 males 7.6035 females
Step-by-step explanation:
The first way to calculate the expected uses the marginal percentages. If sex is not related to flavor preference, you would expect the same percentages of males to prefer the same flavors as females. Since overall 20.71% prefer vanilla, you would expect 20.71% of males to prefer vanilla. Now, 20.71% of 84 people is 17.3964, so this is how many males you would expect to prefer vanilla. You would also expect 20.71% of the females to prefer vanilla, which is 17.6035. So you'd expect 17.3964 males and 17.6035 females to prefer vanilla.
