pls help with steps The president of the student council wants to survey the student population about parking. She decides to take a random sample of 100 of the 1,020 students at the school. She gets an alphabetical list of the students, and numbers them from 0001 to 1020. Then, using a random number table, and starting at a random line, she selects 100 unique numbers between 0001 and 1020. Is this a simple random sample? No, because the sample could contain repeating numbers. No, because the sample could contain numbers other than numbers between 0001 and 1020. Yes, because each student and sample of 100 has the same chance of being selected. Yes, because each student is represented by a 4-digit number from 0001 to 1020.

750 Chapter 30: Representing and Interpreting Data with One Variable 3. JA shoe factory is making a new shoe style to sell to women in a small country in the Pacific. To determine what sizes and how many of each size to manufacture, they collected a random sample of 50 women and measured their shoe sizes. Here are the results: 5.5 6.5 5.5 4.5 5 6. 5.5 5.5 6.5 6 5.5 4.5 5 6. 5.5 6 6. 5 6.5 7 6. 6.5 5 6.5 5.5 5.5 7 6.5 7.5 5.5 6 5.5 6.5 7.5 4.5 4 5.5 6 5 5 6.5 5 4 6. 5.5 Calculate the mean and standard deviation of the sizes and interpret the results in terms of what relative quantities of which sizes the factory should make. Then find the five-number summary and decide which set of information gives you more assistance in making a decision for the shoe factory.

If not, then we know that the two events are Event 2: Spin the spinner 3 times in a row. a. Find the probability that you get these three spins: 2, 2, 2. b.
