A random sample ofn= 15 heat pumps of a certain type yielded the following observations on lifetime (in years): 2.01.36.01.95.15.41.05.315.74.74.83.9 12.25.34.6 According to the manufacturer, the lifetime for these heat pumps is more the 7 years.Compute the provided data and complete the blanks below by filling the required information based on the provided data. The 90%confidence limits for this analysis are Blank 1 and Blank 2, and the and the 95% confidence limits are Blank 3 and Blank 4. By using a t-test at 95% confidence level, the t-value calculated is Blank 5, which is Blank 6 (greater/less) the critical value of Blank 7. Therefore the lifetime forthese heat pumpsis Blank 8 (significantly/ not significantly) different from the claims by the . Blank 1 Blank 2 Blank 3 Blank 4 Blank 5 Blank 6 Blank 7 Blank 8
