Question

1 Using the binomial distribution, perform the following tests of proportion hypotheses: a) H0: P = 0.4 H1: P < 0.4 With n = 11 at a significance level of 5% with the number of successes X=2 b) H0: P = 0.3 H1: P > 0.3 With n = 10 at a significance level of 1% with the number of successes X=8

          1 Using the binomial distribution, perform the following tests of proportion hypotheses:

a) H0: P = 0.4
H1: P < 0.4
With n = 11 at a significance level of 5% with the number of successes X=2

b) H0: P = 0.3
H1: P > 0.3
With n = 10 at a significance level of 1% with the number of successes X=8

Step 1

4. The test statistic for a binomial distribution is \( X \), the number of successes. In this case, \( X = 2 \). We calculate the probability of getting 2 or fewer successes under the null hypothesis, \( P = 0.4 \), using the cumulative distribution function Show more…
