ural area is 8290 dollars. You believe this value is is too low, so you sample 15 rural families and find the ollowing costs (in dollars) of raising a child from birth to age 2. he U.S. 286, 8411, 8264, 8418, 8247, 8425, 8319, 8240, 8375, 8461, 8235, 8477, 8313, 8339, 8256 Conduct a hypothesis test based on this sample data, with a = 5%. Answer the question, is the mean cost of aising a child greater than 8290 dollars? a) State the hypotheses: Ho: The population mean cost in dollars of raising a child from birth to age 2 is equal to 8290 o dollars. Symbols: O 4 - 00- u0 0 , - O 8290 H: The population mean cost in dollars of raising a child from birth to age 2 is more than O 8290 o dollars.

Why? O We are provided with i. O We are not provided with the population standard deviation. O The size of n< 30. O We are provided with o for the population. (e) State the decision rule: d at a = 5 % if the p-value of the Reject HO and accept Ha V sample statistic is Select an answer (f) Experiment: Symbol of the sample statistic: Op Op Or O - I2 OPi - P2 Value of the sample statistic rounded to 2 decimal places: P-value of the sample statistic rounded to 4 decimal places: (g) Conclusion: Reject HO and accept Ha V o at a = 5 (h) Answer the question: Is the mean cost of raising a child greater than 8290 dollars? O Yes, because the p-value is greater than alpha. O No, because the p-value is less than alpha. O Yes, because the p-value is less than alpha. O No, because p-value is greater than alpha.
