An interactive poll found that 307 of 2,245 adults aged 18 or older have at least one tattoo. (a) Obtain a point estimate for the proportion of adults who have at least one tattoo. (b) Construct a 90% confidence interval for the proportion of adults with at least one tattoo. (c) Construct a 98% confidence interval for the proportion of adults with at least one tattoo. (d) What is the effect of increasing the level of confidence on the width of the interval? (a) p = |0.137 (Round to three decimal places as needed.) (b) Construct the 90% confidence interval. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. Lower bound: Upper bound: (Round to three decimal places as needed.) B. The requirements for constructing a confidence interval are not satisfied. (c) Construct the 98% confidence interval. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. O A. Lower bound: Upper bound: (Round to three decimal places as needed.) O B. The requirements for constructing a confidence interval are not satisfied.

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.
