Test the claim that the mean GPA of night students is larger than 3.3 at the 0.005 significance level.The null and alternative hypothesis would be: H0:μ ≤ 3.3H1:μ > 3.3 Based on a sample of 50 people, the sample mean GPA was 3.34 with a standard deviation of 0.05The test statistic is:  (to 2 decimals)The p-value is:  (to 2 decimals)

In recent years, approximately 55% of eligible voters take the time to vote in presidential elections. A poll based on a random sample of 200 eligible voters finds that 128 plan to vote in the next presidential election.    Does this data provide convincing evidence at the ?α = 0.05 level that the proportion of eligible voters who will take time to vote in the next presidential election differs from 0.55?
