After examining over one million online restaurant re- views and the associated weather conditions, Bakhshi, Kanuparthy, and Gilbert (2014) reported signicantly higher ratings during moderate weather compared to very hot or very cold conditions. To verify this result, a researcher collected a sample of n = 25 reviews of local restaurants over an unusually hot period dur- ing July and August and obtained an average rating of M = 7.29. The complete set of reviews during the previous year averaged p. = 7.52 with a standard deviation of o = 0.60. a. Can the researcher conclude that reviews during hot weather are signicantly lower than the genera] popu- lation average? Use a one-tailed test with or = .05. 1). Compute Cohen's d to measure effect size for this study. e. Write a sentence demonstrating how the outcome of the hypothesis test and the measure of effect size would appear in a research report
