The table shows the percentage of students in each of three grade levels who list soccer as their favorite sport. soccer sophomores (35%) 50% juniors (33%) 45% seniors (32%) 30% total (100%) (0.5)(0.35) + (0.45)(0.33) + (0.32)(0.3) = 0.4195 or about 42% find the probability that the student is a junior, given that soccer is the favorite sport listed. p(junior | soccer) = %

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
