Editing Voice Editor 3. Work through this hypothesis test using the prompts below. In other words, finish the sentences I have started. A sample of 12 account balances of credit company showed a mean of customer balance of $5,475, but the marketing manager claimed that the mean balance for the population was $5,350. The marketing manager did NOT have the population standard deviation, but the sample standard deviation was found to be $150. Use the p-value approach to conduct a full hypothesis test (all steps) that can be used to determine whether the mean of all account balances is significantly different from $5,350. Let a = .05. To help you go through the steps of hypothesis testing, follow these prompts: The null hypothesis is The alternative hypothesis is This test is (choose 1: one-tailed / two-tailed) because the last sentence contains the words (choose 1: greater than / less than / different from) I will use a (choose 1: t / z) in my formula because I have calculated the value of t (or z) to be Insert your work for calculating t or z) I have used t (or z) to get the value of p (most likely from a chart or computer printout - provide that printout). My p value is Alpha which is given in the problem, is When I compared p to alpha, p is (choose 1: greater than less than) alpha. Because of this, I know I should (choose 1: reject . fail to reject) my null hypothesis. Choose one: In summary, the mean balance is different than $5350 / In summary, the mean balance is NOT different than $5350
