In February 2021, Pew Research asked 2,596 random US adults what gives them meaning in life. 17% of respondents said, "occupation andcareer. We know that the proportion of the sample who answer "occupation and career" will vary in repeated sampling. In repeated sampling, thesample proportion, p-hat, has an approximately normal distribution with mean 0.17 and standard deviation 0.007. Use this information to answerthe questions below. Show your work for each question and round all numeric answers to 3 decimal places.a) Find the probability that at least 0.175 of a random sample of 2,596 US adults respond "occupation and careerb) Find the probability that between 0.159 and 0.179 of a random sample of 2,596 US adults respond "occupation and careerc) What is the sample proportion that cuts off the lowest 10% all proportions for samples of size 2,596?**

A study was conducted to examine the impact of speaking in public on college students. A class of 15 statistics students participated in the study. At the beginning of a lecture the students recorded their systolic blood pressure. During the lecture the instructor called on each student to stand and answer questions about topics in the lecture. After speaking the students once again recorded their blood pressure.
