QUESTION 2 You have joined a light plane manufacturing company. You have four vendors who supply the take-off and landing lights for the plances. The life of thes bulbs seems to be very different. You test 6 bulbs at random from each of the vendors. You set your alpha at 5%. You want to see if there is statistical significance in the means or if the means are only different by normal statistical noise. For your hypothesis test, the null hypothesis is that mean a = mean b = mean c = mean d. The bulb suppliers and the results of the test in hours until failure are in the following table: Silvia Gen Bulb Phill Lite Bright 651 860 1048 951 839 600 806 1077 961 638 785 1082 773 856 858 998 1037 608 1053 759 822 674 1017 839 Use the ANOVA single factor in the Data Analysis add-in in Excel and answer the following questions. Use alpha of .05. The F value is equal to the variance $\boxed{between}$ groups divided by the variance $\boxed{within}$ groups. Our F value is ? $\boxed{\hspace{2cm}}$ (give 2 decimals) Our F critical is? $\boxed{\hspace{2cm}}$ (give 2 decimals) Given our F value and F Critical value, you must (reject or fail to reject) the null? $\boxed{\hspace{4cm}}$ What is the P-value? $\boxed{\hspace{2cm}}$ (three decimals) Given this P-value you must ("reject" or "fail to reject") the null? $\boxed{\hspace{4cm}}$ That is, is there a statistical difference in the life of the bulbs from the vendors? $\boxed{\hspace{2cm}}$ (yes or no)
