Find the margin of error for the given values of c, d, and n. c-0.95, 0-677, n-40 Question 7 Provide an appropriate response. For a sample of 20 IQ scores the mean score is 105.8. The standard deviation, a, is 15. Determine whether a normal distribution or at-distribution should be used or whether neither of these can be used to construct a confidence interval. Assume that IQ scores are normally distributed Question 8 Question 9 Provide an appropriate response. Determine the sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a mean of -2.2. Assume the grade point average of the 125 students has a mean of u-23 1 out of 1 points Question 10 4 Provide an appropriate response. 0 out of 1 points Provide an appropriate response. In a random sample of 28 families, the average weekly food expense was $95.60 with a standard deviation of $22.50. Determine whether a normal distribution or a distribution should be used or whether neither of these can be used to construct a confidence interval. Assume the distribution of weekly food expenses is normally shaped 1 out of 1 points 1 out of 1 points
