Assume that the year has 366 days and all birthdays are equally likely. Rearrange the following steps in the correct order to find the probability that in a group of n people chosen at random, there are at least two born on the same day of the week. A. What is the probability that two people chosen at random were born on the same day of the week?
B. What is the probability that in a group of n people chosen at random, there are at least two born on the same day of the week?
C. How many people chosen at random are needed to make the probability greater than 1/2 that there are at least two people born on the same day of the week?

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
