Apopulation has a mean of 300 and a standard deviation of 70. suppose a sample of size 125 is selected and is used to estimate . use z-table. what is the probability that the sample mean will be within +/- 8 of the population mean (to 4 decimals)? (round z value in intermediate calculations to 2 decimal places.) what is the probability that the sample mean will be within +/- 17 of the population mean (to 4 decimals)? (round z value in intermediate calculations to 2 decimal places.)

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
