The average salary for a civil engineering major is $75,000 with a standard deviation of $10,000. A university wants to determine how well their students in their civil engineering program get paid after graduating. They ask one class of 80 students in a course to give their salaries after graduating. What is the probability the average salary of the 80 students is between $73,000 and $77,000? 0.16 O 0.93 O 0.68 O 0.78
In 2014 the NY Yankees had a team batting average of u=245 (actually .245 but we'll multiply by 1000 so we can avoid decimals). Assuming the distribution of batting averages is normal for 162 games with o- 40, answer the questions below. A. If you randomly select one game from 2014, what's the probability that the team batting average was less than 200? B. The probability is 40 that you will randomly select a game from 2014 in which the team batting average was at least C. If you randomly select one game from 2014, what's the probability that the team batting average was between 245 and 250?

5 It's 75 degrees and sunny here in San Diego this afternoon...," the weatherman droned on, repeating a phrase that probably should have been recorded and played on an endless loop. Tim looked at the previous year's high temperatures and noted that the average was 78 degrees with a standard deviation of 1 degrees and approximated a normal distribution. Armed with this evidence, determine: (a) the probability of a daily temperature between 78 degrees F and 79 degrees F. (b) the probability that the daily temperature exceeds 78 degrees F. (c) the probability that the daily temperature is below 78 degrees F.
