I need help with my stats homework problems. In some problems I have to claim Ho, Ha/ P value. Please help

question1.

In a sample you had 5637 out of 7946 voters who supported a candidate.Test the claim that the proportion of the population who supports the candidate is less than or equal to 70% of the population. Use a significance level of .05.

question 2.

You developed a way to measure anger people.Test the claim that the mean score of anger for younger people is equal to the mean score for older people. Use a significance level of .06.The scores are listed below

Scores for younger people:25, 33, 19, 8, 39, 29, 28, 18, 41, 3, 27, 35, 14, 25, 36, 4, 11

question 3

In a sample of 758 patients is was found that 28% of them had a certain decease.Test the claim that the proportion of people who have the decease is less than or equal to 26%.Use a significance level of .04. Don't forget to multiply the number of people by the percent to figure out the number of successes.

question 4

You want to test the claim that a police department is doing racial profiling when they are pulling people over.In a sample of 351 Black citizens it was found that 89 of them had been pulled over while in another sample it was found that out of 324 of white citizens 51 of them had been pulled over.Test the claim that the two proportions are not equal. Use a significance level of .07.

question 5

Test the claim that the mean of the first population is greater than or equal to the mean of the second population.Use a significance level of .05

Sample 1: sample size n=186 meanx1=26.9

standard deviation s1=3.7

Sample 2: sample sizen=214mean x2=27.3

standard deviation s2=4.1
