For a hypothesis test of H0: p = 0.35 against the alternative Ha: p > 0.35, the z test statistic is found to be 2.45. What can be said about this finding?

From this finding, it can be said that the sample proportion is greater than the population proportion because the test statistic (z = 2.45) is positive.

Step-by-step explanation:

H0: p = 0.35

Ha: p > 0.35

The test is a one-tailed test because the alternate hypothesis is expressed using greater than.

The test statistic (z) for a proportion is given as (p' - p) : sqrt [p (1-p) / n]

p' is sample proportion

p is population proportion

n is sample size

For the test statistic z to be positive, p' must be greater than p.
