k =42, m = 18, n=4
Here we have to test that
, k =sample size = 42
Test statistic:
Z0 = -2.88 (Round to 2 decimal)
Test statistic = z0 = -2.88
P value = P(Z < Z0)
= P(Z < -2.88)
= 0.0020 (From statistical table of negative z values)
P value = 0.0020
Here alpha = level of significance = (2n)% = (2*4)% = 8% = 0.08
Here P value < alpha
So we reject null hypothesis H0

The amount of time it takes a student to solve a homework problem in mathematical statistics (in minutes) follows a normal distribution with unknown mean μ and a variance equal to 9m2. Find the most powerful test to verify the null hypothesis that μ k against the alternative that , 2k on the base of k independent observations, for a significance level of n%. Calculate the power of this test (for the alternative hypothesis). What is the decision,...
k=28 n=1 m=15 1. The amount of time it takes a patient to fully recover from a virus-inflicted illness (in days) follows a normal distribution with unknown mean i and a variance equal to 9m?. Find the most powerful test to verify the null hypothesis that i = k against the alternative that = 2k on the base of k independent observations, for a significance level of n%.

k=42, m=18 n=4 11. Let F:R → R be a function such that (t+m)(n+1) (n+ m F(t) = for t <-m, f or-m <t<n. for n<t<k, for t > k. nA - 1 Find A and B knowing that F is the cumulative distribution function of a random variable X such that P(X = k) = . Please provide only the value of parameter B in the space specified below. ANSWER: B= Solution:
3. (4 points) Let X equal the number of pounds of butterfat produced by a Holstein cow during the 305-day milking period following the birth of a calf. Assume that the distribution of X is N(μ, σ2-1402). To test the null hypothesis Ho : μ-175 against the alternative hypothesis Ha : u 715, let the crtical region be defined by 668.94, where x is the sample mean of n 25 butterfat weights from 25 cows selected at random (a). What...

3. Compare the fits of Equations 26 and 27 using the F-test. If the two equations are significantly different in overall fit, we can conclude that it's likely that Equation 26 is misspecified While the Ramsey RESET test is fairly easy to use, it does little more than signal when a major specification error might exist. If you encounter a sig nificant Ramsey RESET test, then you face the daunting task of figuring out exactly what the error is! Thus,...
