Consider the following hypothesis test: h 0: = 17h a: 17a sample of 40 provided a sample mean of 14.12. the population standard deviation is 4.a. compute the value of the test statistic (to 2 decimals). (if answer is negative, use minus "-" sign.)b. what is the p-value (to 4 decimals)? c. using = .05, can it be concluded that the population mean is not equal to 17? selectyesnoitem 3answer the next three questions using the critical value approach. d. using = .05, what are the critical values for the test statistic (to 2 decimals)? ±e. state the rejection rule: reject h 0 if z is selectgreater than or equal togreater thanless than or equal toless thanequal tonot equal toitem 5 the lower critical value and is selectgreater than or equal togreater thanless than or equal toless thanequal tonot equal toitem 6 the upper critical value. f. can it be concluded that the population mean is not equal to 17?

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
