A sampling distribution (dotplot) for the mean quiz score for a sample n = 30 of STAT101 students is shown below. It was constructed using random samples from population data. If we increased our sample size from 30 to 100, would the standard error of the sample mean be larger, smaller, or the same? Explain your answer in one or two sentences.

Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population proportion p at the giver using the given sample statistics. Claim: p#0.24; a = 0.01; Sample statistics: p = 0.22, n = 200 Can the normal sampling distribution be used? Yes, because both np and nq are greater than or equal to 5. O B. No, because np is less than 5. OC. No, because ng is less than 5. O D. Yes, because pq is greater than a = 0.01. State the null and alternative hypotheses. O A. Ho: ps0.24 H,: p>0.24 B.
