A professor has a class with four recitation groups. Each section has 16 students. Determine whether or not the section choice (different TAS and different days of the week) has any relationship with how students performed on the test. Group-1 67.1 54.1 67.8 70.8 71.4 49.5 60.6 62.9 55.4 57.5 55.7 45.6 65 68.5 74.9 49.1 Group-2 Group-3 73 59.4 68.3 44 69.1 65.5 80.5 54.4 67.7 39.5 91.2 81.7 78 48.7 85.2 74.8 63.2 68.8 69.4 64.6 76.4 51 82.9 70.3 80.7 52.1 68.6 69.9 41.5 71.4 74.5 60.8 Group-4 71.7 67 49.7 56.6 53 65.4 62.8 52.1 55.4 79.2 66.5 65.5 70.9 71.6 57.4 71.2 First, run an ANOVA with this data and fill in the summary table. (Report P-values accurate to 4 decimal places and all other values accurate to 3 decimal places.) Source SS df MS F-ratio P-value Between Within To follow-up, the professor decides to use the Tukey-Kramer method to test all possible pairwise contrasts. What is the Q critical value for the Tukey-Kramer critical range (alpha=0.05)? Use the table below to locate the Q critical value to 4 decimal places.

A population includes elements A, B, C, D, E. Samples are taken 2 elements at a time. What is the value of N? And what is the value of n? Answer using whole number.

7.2.29-T Question Help An IQ test is designed so that the mean is 100 and the standard deviation is 19 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 6 IQ points of the true mean. Assume that o = 19 and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is. (Round up to the nearest integer.)

How many different ways are there to select a group of 4 out of 8 people for a survey?
