I need help with my attached statistics problems. they're attached below with the prompts.

Find the 2-score for the given shaded region under the standard normal distribution. Round your answer to two decimal places. Shaded Area = 0.9.7 Z-SCDFE = In a survey, 15 people were asked how much they spent on their child's last birthday gift. The results were roughlyI bell-shaped with a mean of $32 and standard deviation of $14. Construct a confidence interval at a 93% confidence level. Give your answers to one decimal place. 22.5 X :l: 41.5 The time to assemble a product was recorded for each worker at a company in a sample of 30. A 95% confidence interval for fr is (152, 160) minutes. a.) The individual object in the study was a randomly selected This is computer-graded so use exact wording from the problem above. b.) What was the variable information recorded for each object in the study? This is computer-graded so use exact wording from the problem above. c.) State the statistical interpretation of the confidence interval in the context of this problem. We are 95% confident that v the time to assemble a product of all w| workers at a company is/are between and d.) What is the symbol and value of the point estimate for p! XY minutes e. ) What is the margin of error for the given interval?' minutes f.) Fill in the boxes below to show the relation on the number line between the numeric values of the point estimate and the interval estimate for /4. 11/16/32, 4:24 PM Chapter & Confidence IntervalsThe state of CT claims that the average time on death row is '15 years. A random survey of T5 death rov.r inmates revealed that the average length of time on death row is '116 years with a standard deviation of 5.6 years. Conduct a hypothesis to test the state of CT's claim. What type of test should be run? {I} ztest for the mean =12} t-test for the mean =22} z-test for the proportion The alternative hypothesis indicates a {I} right-tailed test {I} left-tailed test {I} twotailed test Calculate the p-value. What is the decision? {I} We reject the claim that the average time on death ro'nr is 15 years =22} We fail to reject the claim that the average time on death rov.r is 15 years
