Damage to Homes Caused by Burst Piping Can Be Expensive

Damage to homes caused by burst piping can be expensive to repair.By the time the leak is discovered,hundreds of gallons of water may have already flooded the home.Automatic shutoff valves can prevent extensive water damage from plumbing failures.The valves contain sensors that cut off water flow in the event of a leak,thereby preventing flooding.One important characteristic is the time (in milliseconds) required for the sensor to detect the water leak.Sample data obtained for four different shutoff valves are contained in the file entitled Waterflow. Produce the relevant ANOVA table and conduct a hypothesis test to determine if the mean detection time differs among the four shutoff valve models.Use a significance level of 0.05.

A) The ANOVA produces a p-value of 0.033 < alpha = 0.05.Therefore,the null hypothesis is not rejected.There is not sufficient evidence to indicate that the mean detection time differs among the four shutoff valve models
B) The ANOVA produces a p-value of 0.033 < alpha = 0.05.Therefore,the null hypothesis is rejected.There is sufficient evidence to indicate that the mean detection time differs among the four shutoff valve models
C) The ANOVA produces a p-value of 0.000 < alpha = 0.05.Therefore,the null hypothesis is not rejected.There is not sufficient evidence to indicate that the mean detection time differs among the four shutoff valve models
D) The ANOVA produces a p-value of 0.000 < alpha = 0.05.Therefore,the null hypothesis is rejected.There is sufficient evidence to indicate that the mean detection time differs among the four shutoff valve models
