Consider the hypothesis test given by Hop05 H1p

Consider the hypothesis test given by:

Ho=p=0.5

H1:=p<0.5

In a random sample of 225 subjects, the sample proportion is found to be p=0.51.

a. Determine the test statistic.

b. Determine the p-value for the test.

c. Is there sufficient evidence to justify the rejection of Ho at the a=0.01 level?

a)test static = (x-mean)*sqrt(n)/s.d

here mean =0 varance=1

test statistic = 0.51*15=7.65

b)0.52

c)yes
