Moviegoers The average "moviegoer" sees 8.5 movies a year. A moviegoer is defined as a person who sees at least one movie in a theater in a 12-month period. A random sample of 46 moviegoers from a large university revealed that the average number of movies seen per person was 9.8. The population standard deviation is 3.2 movies. At the 0.01 level of significance, can it be concluded that this represents a difference from the national average? Part: 0/5 Part 1 of 5 State the hypotheses and identify the claim with the correct hypothesis. Ho (Choose one) H₂: (Choose one) This hypothesis test is a (Choose one) test. H D>O - D X D«

PartA A random sample of 16 registered nurses in a large hospital showed that they worked on average 44.3 hours per week. The standard deviation of the sample was 2.8. Estimate the mean of the population with 90% confidence. Assume the variable is normally distributed. Round intermediate answers to at least three decimal places. Round your final answers to one decimal place. ____<p>_ Part B For a sample of 4 operating rooms taken in a hospital study, the mean noise level was 38 decibels and the standard deviation was 11.7. Find the 95% confidence interval of the true mean of the noise levels in the operating rooms. Assume the variable is normally distributed. Round your answers to at least two decimal places. ____Y_
