Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.)A recent study at a university showed that the proportion of students who commute more than 15 miles to school is 25%. Suppose we have good reason to suspect that the proportion is greater than 25%, and we carry out a hypothesis test. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. Ho: 0 H;: D OA researcher selects a sample and administers a treatment for anxiety to the individuals in the sample. If the sample is used for a hypothesis test, what does the null hypothesis (Ho) put forth about the treatment? O The treatment has an effect on anxiety. O The treatment divides each anxiety score by a constant. O The treatment multiplies each anxiety score by a constant. The treatment has no effect on anxiety.Let’s assume the average income for all majors in the School of Engineering is $80,000.

The scientist, believing that u is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.9 pounds and the standard deviation to be 1.6 pounds. Based on this information, answer the questions below.The proportion of defective items is not allowed to be over 12%.
