A television sports commentator wants to estimate the proportion of citizens who "follow professional football." Complete parts (a) through (c). Click here to view the standard normal distribution table_(page 1). Click here to view the standard normal distribution table (page 2). (a) What sample size should be obtained if he wants to be within 2 percentage points with 94% confidence if he uses an estimate of 48% obtained from a poll? The sample size is |. (Round up to the nearest integer.) (b) What sample size should be obtained if he wants to be within 2 percentage points with 94% confidence if he does not use any prior estimates? The sample size is |. (Round up to the nearest integer.) (c) Why are the results from parts (a) and (b) so close? O A. The results are close because 0.48(1 – 0.48) = 0.2496 is very close to 0.25. O B. The results are close because the margin of error 2% is less than 5%. O c. The results are close because the confidence 94% is close to 100%.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
