A group of 100 people, who lived at varying distances (in kilometers) from an island nuclear power station, were asked if they thought a full evacuation of the area was required, when it went critical. The researches wanted to know if the opinion to evacuate or not depended on how far from the reactor people lived, Partial results of the questionnaire are shown in the table below. 0-3 km distance 3 -6 km distance 6 + km distance Totals Evacuation needed X X X 54 Evacuation not X XX needed Totals 33 32 XX XX You are doing a Chi Square test for independence. XX denotes row/column totals. Compute the expected number of people living 6+km away who would prefer NOT to evacuate. Give your answer to 2 decimal places.

Hi, just type out the explanation and steps out for all of them.

NOTE: This problem has many steps. You are asked to enter intermediate values in the process. These answers will require a fixed number of decimal points. However, you MUST ALWAYS REMEMBER that you are not using the rounded numbers in your future calculations. The only exception to this is that you may use z-scores rounded to three decimal places (of course, you also may use the unrounded version as well).In a certain school district in a large metropolitan area, the SAT scores over that past five years are normally distributed with a mean of 1533. Furthermore, P20 is 1277.For a normal distribution, what is the z-score for the 20-th percentile? z = Incorrect (Enter answer rounded to three decimal places.)Using this information, what is the standard deviation of this population of SAT scores? sigma = Incorrect (Enter answer rounded to the nearest whole number.)For a normal distribution, what is the z-score for the 95-th percentile? z = Correct (Enter answer rounded to three decimal…
