A company's cereal boxes advertise that 9.65 ounces of cereal are contained in each box. In fact, the amount of cereal in a randomly selected box follows a normal distribution with mean LaTeX: \muμ = 9.70 ounces and standard deviation LaTeX: \sigmaσ = 0.03 ounces. A quality control worker selects a random sample of 5 cereal boxes. What is the standard deviation LaTeX: \sigma_{\frac{ }{x}}σ x(in ounces) of this sampling distribution?

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.
