Question
of 6.9 years. Conduct a hypothesis test to A random survey of 75 death row inmates revealed that the mean length of time on death row is 17.1 years with a standard deviation determine if the population mean time on death row could Ikely be 15 years Part (a) Part(b Part (c) D Part () D Part it mathPad Part 0 State the distribution to use for the hypothesis test. (Enter your answer in the form z or ior where d is the degrees of freedom.) Part Find the p-value. (Round your answer to four decimal places)Explanation / Answer
I) Z-test
J) Z = (17.1 - 15)/(6.9/sqrt (75))
= 2.64
P-VALUE = 2 * P(Z > 2.64)
= 2 * (1 - P(Z < 2.64))
= 2 * (1 - 0.9959)
= 2 * 0.0041 = 0.0082
