Members of a bowling league play thousands of combined games over the course of a season. Suppose that the scores of individual games have a known standard deviation of Ο=30 pins. Isla plans on taking a random sample of n games from this population to make a 95% confidence interval for the mean score. She wants the margin of error to be no more than 10 pins. Which of these is the smallest approximate sample size required to obtain the desired margin of error?
9 games
30 games
35 games
43 games
55 games

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to β(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from β6. the value of y must be positive since the variable is inside absolute value signs.
