When engaging in weight-control (fitness/fat burning) types of exercise, a person is expected to attainapproximately 60% of his or her maximum heart rate. For 20-year-olds, this rate is approximately 120bpm. A simple random sample of thirty 20-year-olds was taken, and the sample mean was found to be107 bpm, with a standard deviation of 45 bpm. Researchers wonder if this is evidence to concludethat the expected level is actually lower than 120 bpm.Report a 95% confidence region for the mean level of heart rate for this group.the mean level of heart rate is lower than 120.96the mean level of heart rate is greater than 114.47the mean level of heart rate is greater than 117.67the mean level of heart rate is lower than 114.47

From the given information, The average value is lower than 120 bpm. Null Hypothesis: H0: The…

Answered: When engaging in weight-control…

A sports dataset collected over ten years shows that the total number of baskets scored by an NBA player in a season depends on the amount of his yearly salary. The sample mean and standard deviation of salaries of studied players over this period are $1.1 million dolars and $0.4 million dollars, respectively. The sample mean and standard deviation of total number of scored baskets in a season are 701.7 and 57.1, respectively. The correlation coefficient between the yearly salary and the number of baskets is 0.75. Based on this data, fit a linear regression model and predict the total number of baskets that will be scored in a season by an NBA player with salary $3.9 million dollars a year. Write your answer as an integer, by rounding your solution to the nearest integer. Number of baskets in a season:

The salary of a recent graduate from a northeast university with an MBA follows a normal distribution with a mean starting salary of $78,000 with a standard deviation of $15,000. You apply the normal model and discover that approximately 7.1% receive a starting salary of more than $100,000. A university administrator surveyed a random sample of 450 of their recent graduates that earned an MBA. How many of these graduates would you expect to receive a starting salary of more than $100,000? Explain.
Many psychologists are concerned that the average level of anxiety in children has increased over the past 40 years. In the 1980s, the population average score on the Child Manifest Anxiety Scale (CMAS) was 15.1. In 2021, a random sample of 101 children was tested with CMAS. The mean for the sample was 16.1 with the standard deviation of 4. Is there enough evidence to claim that there has been a significant change in the average level of anxiety since the 1980s? Conduct the appropriate statistical test (two- tailed) with a = .05. Based on the estimated Cohen's d, the magnitude of change in the average level of anxiety since the 1980s could best be qualified as: O Very large O Large O No change OSmall
