To find the probability that the actual costs will exceed the budgeted amount of $648, we need to calculate the Z-score for this budget and then find the probability of the costs being greater than this Z-score. Z = ($648 - $635) / $40 = 0.325 The probability can be calculated by finding P(Z > 0.325) using a standard normal distribution table or

A recent Harris poll was conducted with a random sample of 1994 Americans, and they were asked the question: "How concerned are you about the economy as a result of COVID-19?" The results of the poll lead to a 95% confidence interval (0.488, 0.531) for respondents of "Very concerned". Choose the best interpretation of the interval below. A. There
