According to a study, the proportion of people who are satisfied with the way things are going in their lives is 0.86. Suppose that a random sample of 100 people is obtained. Complete parts (a) through (e) below. Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). O A. The response is qualitative because the number of people satisfied can be counted. O B. The response is quantitative because the number of people satisfied can be counted. O C. The response is quantitative because the responses can be classified based on the characteristic of being satisfied or not. YD. The response is qualitative because the responses can be classified based on the characteristic of being satisfied or not. (b) Explain why the sample proportion, p, is a random variable. What is the source of the variability? The sample proportion p is a random variable because the value of p represents a random person included in the…

It is claimed that the proportion of adults with at least one chronic disease in a certain country might be more than the reported number, which is only 25%. A random sample of 85 adults are surveyed, of which 28 are found to suffer from at least one chronic disease. Use a 0.01 level of significance to test the above claim.

A trucking company determined that the distance traveled per truck per year is normally distributed, with a mean of 80 thousand miles and a standard deviation of 10 thousand miles. Compa below. (...) The percentage of trucks that can be expected to travel either less than 60 or more than 95 thousand miles in a year is 8.96 %. (Round to two decimal places as needed.). c. How many miles will be traveled by at least 85% of the trucks? The number of miles that will be traveled by at least 85% of the trucks is 69636 miles. (Round to the nearest mile as needed.) d. What are your answers to parts (a) through (c) if the standard deviation is 8 thousand miles? If the standard deviation is 8 thousand miles, the proportion of trucks that can be expected to travel between 66 and 80 thousand miles in a year is (Round to four decimal places as needed.) If the standard deviation is 8 thousand miles, the percentage of trucks that can be expected to travel either less than 60 or more than 95 thousand…
