(1 point) How many rounds of golf do those physicians who play golf play per year? A survey of 12 physicians revealed the following numbers: 7, 41, 16, 3, 32, 41, 19, 15, 18, 33, 14, 50 Estimate with 97% confidence the mean number of rounds played per year physicians, assuming that the population is normally distributed with a standard deviation of 6. Note: For each confidence interval, enter your answer in the form (LCL, UCL). You...

(1 point) It is known that the amount of time needed to change the oil in a car is normally distributed with a standard deviation of 3 minutes. A random sample of 115 oil changes yielded a sample mean of 27 minutes. Compute the 92% confidence interval estimate for the population mean. Note: For each confldence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the contfidence limits. Confdence Interval-

Question 1 (1 point) A customer wants to estimate the average delivery time of a pizza from the local pizza parlor. Over the course of a few months, the customer orders 29 pizzas and records the delivery times. The average delivery time is 23.69 with a standard deviation of 7.212. If the customer estimates the time using a 95% confidence interval, what is the margin of error? Question 1 options: 1) 0.7137 2) 2.2782 3) 2.7433 4) 1.3392 5) 2.739...

The mean number of sick days an employee takes per year is believed to be about 10. Members of a personnel department do not believe this figure. They randomly survey 8 employees. The number of sick days they took for the past year are as follows: 10; 5;15; 5; 11; 10; 8; 10. Let x the number of sick days they took for the past year. Should the personnel team believe that the mean number is about 10? Conduct a...

The accompanying data contain the rating of large and medium size airports in a particular country, based on a 1000-point maximum. Complete parts (a) through (d) below . a. For large and medium airports separately, construct a 95% confidence interval estimate for the population mean rating The 95% confidence interval estimate for the population mean rating for large size airports is nothing less than or equals≤muμless than or equals≤nothing. (Round to the nearest integer as needed.) The 95% confidence interval...
