An insurance agent says that the mean cost of insuring a two-year old sedan (in good condition) is less than $1200. A random sample of 7 similar insurance quotes has a mean cost of $1125, and a standard deviation of $55. Is there enough evidence to support the agent's claim at 0.10? Assume the population is normally distributed.

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.
