a)A manufacturer of sprinkler systems designed for fire protection claims that the average activating temperature is 135 degrees. To test this claim, a (type in "left", "right", or "two") -tailed hypothesis should be set up. b)A random sample of 32 systems has a mean activation temperature 134 degrees with a standard deviation of 3.3 degrees. What is the P-value for this sample? Round to the nearest thousandth. c)At significant level 0.1, is there enough evidence to reject the manufacturer's clam?...

Question 2 A manufacturer of sprinkler systems used for fire protection in office buildings claims that the true average system-activation temperature is 130 degrees. A sample of 9 systems when tested yields a sample average activation temperature of 131.08 degrees. If the distribution of activation times is normal with standard deviation 1.5 degrees, test at the 1% level of significance to see if the data shows evidence that is different from the manufacturers claim. (a) State the null and alternative...

A manufacturer of sprinkler systems used for fire protection in office buildings claims that the true average system-activation temperature is 130oF. A sample of n = 9 systems, when tested, yields a sample average activation temperature of 131.08oF. Suppose the distribution of activation temperature is normal with standard deviation 3.0 oF. Denote the true average system-activation temperature by µ ( oF). Consider testing H0 : µ = 130 versus Ha : µ 6= 130 at the significance level α =...

Question 8 2 pts A sprinkler manufacturer claims that the average activating temperatures is at least 134 degrees. To test this claim, you randomly select a sample of 32 systems and find the mean activation temperature to be 133 degrees. Assume the population standard deviation is 3.3 degrees. Find the standardized test statistic and the corresponding p-value O z-test statistic - -1.71, p-value-0.0432 O z-test statistic -1.71, p-value -0.0865 O z-test statistic -1.71, p-value- 0.0865 O z-test statistic - 1.71,...
