Problem
A publisher reports that $39 \%$ of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually more than the reported percentage. A random sample of 400 found that $45 \%$ of the readers owned a laptop. Is there sufficient evidence at the 0.05 level to support the executive's claim? Step 1 of 7 : State the null and alternative hypotheses.
Solution
Step 1 ：State the null and alternative hypotheses.
Step 2 ：The null hypothesis (H0) is: \(p = 0.39\)
Step 3 ：The alternative hypothesis (H1) is: \(p > 0.39\)
