A manager on an assembly line wants to see if there is they can speed up production by implementing a new switch for their conveyor belts. There are four different switches to choose from and replacing all the switches along the assembly line will be quite costly. They test out each of the four designs and record assembly times. Use the ANOVA table below with a = 0.05 to see if there is a statistically significant difference in the mean times. The hypotheses are: Ho: M1 = H2 = H3 = M4 Hi: At least one mean is different. Source SS df MS F Between 80.3951 3 Within 875.9111 87 Total 956.3062 90
a) Find the test statistic. Round answer to 4 decimal places. b) Choose the correct decision and summary. Do not reject Ho, there is not enough evidence to support the claim that there is a difference in the mean assembly times for the four types of switches Do not reject Ho, there is enough evidence to support the claim that there is a difference in the mean assembly times for the four types of switches Reject Ho, there is enough evidence to support the claim that there is a difference in the mean assembly times for the four types of switches By Reject Ho, there is not enough evidence to support the claim that there is a difference in the mean assembly times for the four types of switches.
