The Brac University Basketball Team is looking for new players to join the team. The heights of all the try-out participants is known to follow a normaldistribution with a mean of 171 cm and a standard deviation of 7 cm. To have a shot at joining the team, one must have a height between 168 cm and179 cm; otherwise the team may end up imbalanced and incompatible.a. What is the probability that a randomly selected try-out participant will not satisfy the height requirements?Answer in exact fraction, or rounded to at least 4 decimal places.b. Determine the 91 percentile value for the height of the participants.Answer in exact fraction, or rounded to at least 2 decimal places.cmc. Participants who fall among the lower 13.24% of the accepted height range are required to qualify in some additional physical tests. So, whatshould the minimum height of an applicant be if they are to skip the additional physical tests?Answer in exact fraction, or rounded to at least 2 decimal places.cm

The University of Montana admission standards require students to have an ACT score of at least 22. We know that Montana ACT scores are normally distributed with a mean of 20.1 and a standard deviation of 4. A: Students in Oregon have a mean ACT score of 21.1 with a standard deviation of 2.8. If we chose one student each at random from Oregon and from Montana, which student would be more likely to meet the ACT requirements of the University of Montana? Explain your answer using the appropriate statistics and a correctly labeled and shaded normal distribution. B: We know that the Montana ACT scores are normally distributed with a mean of 20.1 and a standard deviation of 4. Assume that the top 2% of individuals in the state are eligible for a state-funded scholarship. What score does an individual need on the ACT to be eligible? Explain your answer using the appropriate statistics and a correctly labeled and shaded normal distribution

Records from the Washington Department of Licensing show that 47 former SFCC business students have incorporated their own businesses in the last five years. Eight of these students are selected at random and contacted. Each is asked how many people are employed by their corporation. The responses are: 7, 12, 13, 17, 10, 5, 10, and 6 employees. What is your best estimate of the standard deviation of the number of employees for all 47 corporations?
