Answer:
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.
