Question number 1 1) A random sample of 45 restaurants gave a mean profit per employee of €350. Thepopulation standard deviation is known and its value is €55. Find the 95%confidence interval for the mean profit per employee for all restaurants.2) A power company is promoting high-efficiency bulbs by giving a rebate to all buyersof such bulbs. The service desk manager knows that the employee time required toprocess such a rebate follows the normal distribution. The manager monitored arandom sample of 16 rebate processes and measured the employee time spent foreach. The sample mean was 3.7 minutes and the sample standard deviation was 1.7minutes. Compute the 99% confidence interval for the mean employee time requiredto process all of these rebates

Suppose that for a random sample of 200 firms that revalued their fixed assets, the mean ratio of debt to tangible assets was 0.517 and the sample standard deviation was 0.148. For an independent random sample of 400 firms that did not revalue their fixed assets, the mean ratio of debt to tangible assets was 0.489 and the sample standard deviation was 0.158. Find a 99% confidence interval for the difference between the two population means.

In the network of centers for minors in a certain region, it is necessary to check if for a certain group the average number of escape attempts by inmates is greater than 3, 20 minors are randomly selected, obtaining that the average number of attempts is 3.5 with a standard deviation of 2.7 For a confidence level of 99%, can it be considered that the average number of escape attempts is actually greater than the value initially proposed?
A random sample of 40 adults with no children under the age of 18 years results in a mean daily leisure time of 5.64 hours, with a standard deviation of 2.43 hours. A random sample of 40 adults with children under the age of 18 results in a mean daily leisure time of 4.09 hours, with a standard deviation of 1.63 hours.

Suppose a paper reported that the freshman year weight gain for the students in a representative sample of 103 freshmen at a midwestern university was 5.6 pounds and that the standard deviation of the weight gain was 6.9 pounds. The authors also reported that 75.7% of these students gained more than 1.3 pounds, 17.4% maintained their weight within 1.3 pounds, and 6.8% lost more than 1.3 pounds. C) Calculate a 95% confidence interval (in pounds) for the population mean weight gain of freshmen students at this university. (Round your answers to three decimal places.)
The St. Lucie County Economic Development Board needs to estimate the proportion of all county residents who have earned at least a bachelor's degree. A random sample conducted by the St. Lucie County Economic Development Board found that 20.8% of all county residents held at least a bachelor's degree.Find three different confidence intervals - one with sample size 487, one with sample size 777, and one with sample size 938. Assume that 20.8% of the county residents in each sample have earned at least a bachelor's degree. Notice how the sample size affects the margin of error and the width of the interval.Report confidence interval solutions using interval notation. Report all solutions in percent form, rounded to two decimal places, if necessary.
