Each child in a sample of 64 low-income children was administered a language and communication exam. The sentence complexity scores had a mean of 7.61 and a standard deviation of 8.93. complete parts a through d.
a. From the sample, estimate the true mean sentence complexity score of all low-income children.
b. Form a 90% confidence interval for the estimate, part a
c. Give a practical interpretation of the interval, part b.
d. Suppose the true mean sentence complexity score of middle-income children is known to be 15.55. Is there evidence that the true mean for low-income children differs from 15.55?

There are many ways to measure the reading ability of children. Research designed to improve reading performance is dependent on good measures of the outcomes. One frequently-used test is the DRP, or Degree of Reading Power. It is known that the distribution of DRP scores is normally distributed. A researcher suspects that the mean score µ of all third-graders in Henrico County Schools is different from the national mean, which is 32. To test her suspicion, she administers the DRP...

You are curious about the average number of yards Matthew Stafford throws for each game for the Detroit Lions. You randomly select 23 games and see that the average yards per game is 344.5 with a standard deviation of 27.8 yards. You want to create a 95% confidence interval for the true average number of yards per game he throws. What is the margin of error for this estimate? Question 1 options: 1) 1.5833 2) 5.7967 3) 12.0216 4) 9.9538...
