QUESTION:
Refer to Exercise 8.
a. Find a 99% upper confidence bound for the mean temperature.
b. The claim is made that the mean temperature is less than 349.5◦F. With what level of confidence can this statement be made?
ANSWER:
Solution 15E
Step1 of 3:
Let us consider a random variable X it represents the oven temperature. Here random variable X follows normal distribution with mean standard deviation
and n = 67.
That is
The probability density function of normal distribution is given by
,
.
Where,
x = random variable
= mean of X
= variance of X
= standard deviation os X
= mathematical constant and its value is 3.14
Here our goal is:
a). We need to find a 99% upper confidence bound for the mean temperature.
b). We need to find level of confidence can this statement be made by taking the mean temperature is less than 349.5°F.
