Use technology students as population 1 and health students as population 2: You suspect that a higher proportion of technology students read their textbook than health students. You took a sample from each group. 43 of 80 technology students said that they read their text, while 34 of 60 health students said so.

Question: a.) What is the sample proportion for technology students (to three decimal places)?

b.) What is the point estimate for the difference between population proportions (to at least three decimal places)?

c.) The next several questions refer to determing a confidence interval for the difference in population proportions, at the 95% confidence level. What is the z or t score to be used (to at least three decimals)?

d.) What is the margin of error (E) (to at least two decimals)?

e.) What is the LOWER limit of the interval (to at least two decimals)?
