Chapter 9 Problem A: The drying time of a certain type of paint under specified test conditions is normally distributed with a = 9. Let u denote the ture average drying time when the additive is used. The hypotheses Ho: x= 75 versus He: x<75 are to be tested using a random sample of n = 25 observations. ---- 1.

A)The drying time of a type of paint under specified test condition is known to be normally distributed with an assumed mean value of 75 and a standard deviation of 9. Test the hypothesis H0: µ=75 vs. Ha: µ<75 from a sample of 25 observations. How many standard deviations on the mean (standard error on the mean) away from the null value is the sample mean of 72.3? B)The drying time of a type of paint under specified test condition...

The drying time of a type of paint under specified test condition is known to be normally distributed with an assumed mean value of 75 and a standard deviation of 9. Test the hypothesis H0: µ=75 vs. Ha: µ<75 from a sample of 25 observations with a sample mean value of 72.3. What is the p-value for this test (to 4 decimals)?

The drying time of a certain type of paint under specified test conditions is known to be normally distributed with mean value 75 min and standard deviation 9 min. Chemists have proposed a new additive designed to decrease average drying time. It is believed that drying times with this additive will remain normally distributed with σ = 9. Because of the expense associated with the additive, evidence should strongly suggest an improvement in average drying time before such a conclusion...
