Question 6Is smoking during pregnancy associated with premature births? To investigate this question,researchers selected a random sample of 118 pregnant women who were smokers. The averagepregnancy length for this sample of smokers was 255 days. From a large body of research, it isknown that length of human pregnancy has a standard deviation of 16 days. The researchersassume that smoking does not affect the variability in pregnancy length.Find the 95% confidence interval to estimate the length of pregnancy for women who smoke.(Note: The critical z-value to use, Ze, is: 1.960))Your answer should be rounded to 3 decimal places.

In an effort to estimate the mean amount spent per customer for dinner at a major Atlanta restaurant, data were collected from 64 randomly selected customers. The sample mean was calculated as $27.75 with a sample standard deviation of $4. We wish to develop a 91% confidence interval for the mean amount spent per customer for dinner at this restaurant. Assume that the standard deviation of the amounts spent by ALL customers is $4.30. What is the variable of interest? ["", "", ""] And is this variable Quantitative or Qualitative? ["", ""] In other words: what is the one piece of info we care about for each individual in the population? Is it a quantitative measurement? Or do we determine if each individual belongs to a certain category (referred to as success) or not (failure)? If it is a quantitative measurement, then the population is filled with numbers. Otherwise, the population is filled with…
