Perfоrm the fоllоwing hypothesis test: A rаndom survey of 75 deаth row inmаtes revealed that the mean length of time on death row is 17.4 years with a standard deviation of 6.3 years. Conduct a hypothesis test to determine if the population mean time on death row could likely be 15 years. (You may assume that the underlying population is normally distributed.) Is this a test of one mean or proportion? [a1] State the claim in mathematical form. [a2] (This is the [a16] hypothesis.) Identify the null and alternative hypothesis. H0: [a3] HA: [a4] We will use the [a5] distribution because the population standard deviation is [a6]. Is this a left, right, or two-tailed test? Pick the matching graph. [a15] A. B. C. State the significance level. α = [a8] Calculate the p-value using technology. p-value = [a7] Compare the p-value to the significance level. p-value [a9] α, meaning that we will [a10] the H0. Therefore, because we [a11] the H0 and the original claim was the [a12], we find that there [a13] sufficient evidence to [a14] of the claim that the population mean time on death row could likely be 15 years.
