Prоvide аn аpprоpriаte respоnse.To help consumers assess the risks they are taking, the Food and Drug Administration (FDA) publishes the amount of nicotine found in all commercial brands of cigarettes. A new cigarette has recently been marketed. The FDA tests on this cigarette gave a mean nicotine content of 28.4 milligrams and standard deviation of 2.9 milligrams for a sample of n = 9 cigarettes. The FDA claims that the mean nicotine content exceeds 31.2 milligrams for this brand of cigarette, and their stated reliability is 90%. Do you agree?
Prоvide аn аpprоpriаte respоnse.A simple random sample of size n = 1,300 is obtained from a population whose size is and whose population proportion with a specified characteristic is Describe the sampling distribution of .
Prоvide аn аpprоpriаte respоnse.The U.S. housing market estimates that 31% of all homes purchased in 2019 were considered investment properties. If a sample of 800 homes sold in 2019 is obtained what is the probability that at least 175 homes are going to be used as investment property?

Prоvide аn аpprоpriаte respоnse.A researcher at a major clinic wishes to estimate the proportion of the adult population of the United States that has sleep deprivation. What size sample should be obtained in order to be 95% confident that the sample proportion will not differ from the true proportion by more than 5%?
Prоvide аn аpprоpriаte respоnse.Assume that blood pressure readings are normally distributed with a mean of 117 and a standard deviation of 8. If 100 people are randomly selected, find the probability that their mean blood pressure will be less than 119.
Prоvide аn аpprоpriаte respоnse.When 495 junior college students were surveyed, 145 said they have a passport. Construct a 95% confidence interval for the proportion of junior college students that have a passport. Round to the nearest thousandth. 1.
