Question

For problems 3-9, test the claim using an appropriate hypothesis test. State the critical value(s) of the P-value (you do not need to give both) and whether the claim is rejected, not rejected, supported, or not supported. Test the claim that mu 60, given sigma = 9, n = 70, and F = 6a, Use alpha = 0.0s, A random sample of 33 first graders spend an average of 36.J minutes per day working to homework, with standard derivative9.2 minutes. Test the claim that first graders spend more than 35 minutes per day on average working on homework. Use alpha = 0.0a

Explanation / Answer

4) THE NULL HYPOTHESIS = H0= U = 35

THE ALTERNATE HYPOTHESIS = HA>35

THE ALPHA = 0.01

N = 33

THEREFORE WE CAN TAKE IT TO BE NORMAL

TEST STATIC = (X-MEAN)/(STANDARD DEVIATION/SQRT(N))

= (36.3-35)/(9.2/SQRT(33))

= 0.81

THE P VALUE FOR Z = 0.81

= 0.7910

AS THE P VALUE IS GREATER THEN THE ALPHA = 0.01

THEREFORE WE WILL ACCEPT THE NULL HYPOTHESIS.
