Q3:
A sample of 100 body temperatures has a mean of 98.8℉. Assume that ? is known to be 0.6℉. Use a 0.05 significance level to test the claim that the mean body temperature of the population is equal to 98.6℉, as is commonly believed. Is there sufficient evidence to conclude that the common belief is wrong?
(Use the P-value method where (? < 3.33) = 0.9996)
Q4:
Listed below are the body lengths (in inches) and weights (in lb) of randomly selected bears:
Length
40 64 65 49 47
Weight
65 356 316 94 86
• Find the value of the linear correlation coefficient.
• Letting y represent weights of bears and letting x represent their lengths, find the regression equation.
• Based on the given sample data, what is the best predicted weight of a bear with a length of 72.0 inch?
Question 3)
Answer)
As the population standard deviation is known here, we can use standard normal z table to conduct the test.
Null hypothesis Ho : u = 98.6
Alternate hypothesis Ha : u is not equal to 98.6
This is a two tailed test.
As not equal to sign in alternate hypothesis means two tailed test.
Test statistics z = (sample mean - claimed mean)/(s.d/√n)
Sample mean = 98.8
Claimed mean = 98.6
Sample size N = 100
After substitution z = 3.33
From z table, P(z>3.33) = 0.0004
But our test is two tailed
So, P-Value is = 0.0004*2 = 0.0008
As the obtained P-Value is less than the given alpha of 0.05
We reject the null hypothesis and we do not have enough evidence to support the claim.
