Data Below represent a sample. What is the probability of the population mean to be above 263.1?

Please include Excel Calculations.

a) If you have 4 cousins, what is the probability that 3 or more are male? (Assume male and female are equally likely).

b) In a normal distribution, what percent of scores are in T-score of 51 or higher?

c) If you roll two 6-sided dice, what percent of the time do both dice show numbers from 4 to 6?

d) In an elementary school, the correlation between age and height for all students in the school is _________ than the same correlation for only the fourth graders.

probability 10%. n= 50 find between 15 and 18 times.

Use the normal distribution to approximate the desired probability. A certain question on a test is answered correctly by 24.0 percent of the respondents. Estimate the probability that among the next 166 responses there will be at most 43 correct answers.
