What does The statistical hypotheses consist of?

A USA Today article claims that the proportion of people who believe global warming is a serious issue is 0.63, but given the number of people you've talked to about this same issue, you believe it is less than 0.63. The hypotheses for this test are Null Hypothesis: p ≥ 0.63, Alternative Hypothesis: p < 0.63. If you randomly sample 20 people and 12 of them believe that global warming is a serious issue, what is your test statistic and p-value?   Question 3 options:   1)  Test Statistic: 0.278, P-Value: 0.391   2)  Test Statistic: 0.278, P-Value: 0.609   3)  Test Statistic: -0.278, P-Value: 0.782   4)  Test Statistic: -0.278, P-Value: 0.391   5)  Test Statistic: -0.278, P-Value: 0.609

Suppose you are asked to conduct a two-tailed hypothesis test on the population mean. What type of hypothesis test would you use? Why? What assumptions do you need to make about the process when you are conducting a hypothesis test on the population mean in order for your results to be valid?

Consumers Energy states that the average electric bill across the state is $51.28. You want to test the claim that the average bill amount is actually different from $51.28. What are the appropriate hypotheses for this test?

Consumers Energy states that the average electric bill across the state is $60.07. You want to test the claim that the average bill amount is actually greater than $60.07. What are the appropriate hypotheses for this test?   Question 12 options:   1)  HO: μ ≥ 60.07HA: μ < 60.07   2)  HO: μ = 60.07HA: μ ≠ 60.07   3)  HO: μ > 60.07HA: μ ≤ 60.07   4)  HO: μ ≤ 60.07HA: μ > 60.07   5)  HO: μ < 60.07HA: μ ≥ 60.07

Based on information from a large insurance company, 66% of all damage liability claims are made by single people under the age of 25. A random sample of 51 claims showed that 43 were made by single people under the age of 25. Does this indicate that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company? Give the test statistic and your conclusion.

A publisher reports that 44% of their readers own a particular make of car. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.
