I need help with the second half of C ONLY. 

A random sample of 50 binomial trials resulted in 20 successes. Test the claim that the population proportion of successes does not equal 0.50. Use a level of significance of 0.05.

(a)

Can a normal distribution be used for the distribution? Explain.
No, n·q is greater than 5, but n·p is less than 5.Yes, n·p and n·q are both greater than 5.     No, n·p is greater than 5, but n·q is less than 5.No, n·p and n·q are both less than 5.Yes, n·p and n·q are both less than 5.

(b)

State the hypotheses.
H0: p = 0.5; H1: p > 0.5H0: p = 0.5; H1: p ≠0.5     H0: p < 0.5; H1: p = 0.5H0: p = 0.5; H1: p < 0.5

(c)

Compute . (Enter a number.)
p hat =

Compute the corresponding standardized sample test statistic. (Enter a number. Round your answer to two decimal places.)
