A researcher is testing whether the mean weight of apples from two orchards is the same. A sample of 25 apples from Orchard A has a mean weight of 150 grams with a standard deviation of 15 grams, and a sample of 30 apples from Orchard B has a mean weight of 145 grams with a standard deviation of 10 grams. Test the hypothesis at the 5% significance level.
A researcher is studying the relationship between the number of hours studied (X) and exam scores (Y). The regression equation is given as Y = 50 + 5X. Calculate the predicted exam score if a student studies for 4 hours.
A factory produces light bulbs, and 95% of the bulbs pass the quality control test. If a random sample of 20 bulbs is taken, what is the probability that exactly 18 bulbs will pass the test?

Five randomly selected subjects are given alcohol to produce legal drunkenness and then are given a simulated driving test (scored from a top score of 10 to a bottom score of 0). Five different randomly selected subjects are given marijuana and then the same driving test. Finally, a control group of five subjects is tested for driving while sober. The driving test scores and the One-Way ANOVA table for these data are shown below. Test the hypothesis that there is a difference among the means of the three groups at 1% significance level.
