Explanation / Answer

H0: p <= 0.3

Ha: p > 0.3 (claim)

test statistic: z = 2.27

(a) Since the alternate hypothesis (claim) is p>0.3, this is a right tailed test.

(b) Since the z-value for p = 0.3 is z = 2.27, P-value = P(z>2.27)

= 0.0116

(c) For 0.10 significance level, one tailed critical value = z = 1.2845.

Since, test statistic z = 2.27 > 1.2845

Reject H0, There is sufficient evidence to support the claim that p > 0.3. (option B)
