Question 15 [1 point) Hoping to attract more shoppers downtownI a city builds a new public parking garage in the central business district. The city plans to pay for the structure through parking fees. For a random sample of 46 weekdays, daily fees collected averaged $14900 with a standard deviation of $1100. Find a 90% confidence interval for the mean daily income this parking garage will generate and report the lower limit. Note: 1- Only round your final answer to the nearest integer. Your Answer: :] Answer Question 16 (1 point) The government wants to clamp down on the use of a particular pesticide X in crop- growing. They suggest that a maximum value of 0.05 ppm should be found when crops are screened for this pesticide. A random sample of of crops were selected to test for tfilevel of this pesticide. The sample information is summarized below: n = 150, y = 0.067 ppm. 5 = 0.002 ppm Find the upper bound of the 95% confidence interval for the amount of pesticide present in the crops sampled [Note: For n = 150 and this level of significance, the critical value is t* = 1.976] Note: 1- Round your intermediate numbers to 4 decimal places. 2- Round you final answer to 3 decimal places. Enter your final answer to 3 decimal places.

A sample of employees was randomly selected from each of three companies with different management styles (Authoritarian, Laissez-faire and Participative} and asked to rate their level ofjob satisfaction on a 10-point scale {10 being the highest level of satisfaction). The data collected and partial ANOVA results appear above. Then at u=0.05. by comparing the F- critical value to F statistic valueI we can (you can use the F table in the appendix B of the textbook to find the critical value) 0 reject the null hypothesis and conclude that at least one mean employee job satisfaction ratings are different. 0 conclude that mean employee job satisfaction ratings are all equal across companies with different management styles. 0 support the null hypothesis and conclude that management style does not affect employee job satisfaction rating. 0 fail to reject the null hypothesis.
