Parking Meter Revenue A one-sided confidence interval can be found for a mean by using S S H> X−1₁+√ °² μ< X+1₂√√₁ X-ta or ta where to is the value found under the row labeled One tail. Find two one-sided 90% confidence intervals of the population mean for the data shown, and interpret the answers. The data represent the daily revenues in dollars from 16 parking meters in a small municipality. Round your answers to at least three decimal places. 2.59 1.29 2.39 2.79 0.99 1.04 3.09 2.34 2.49 2.74 2.44 2.34 2.39 2.09 1.79 2.89

Coming to School The time X it takes Mrs. Irvine to drive to work on a randomly selected day follows a distribution that is approximately Normal with mean 22 minutes and standard deviation 5.2 minutes (she is a Statistics teacher, after all): Once she parks in the back parking lot it takes her 4 more minutes to walk to her classroom. Let T = the total time it takes Mrs Irvine to reach her classroom on a randomly selected day, so T = X+4 Describe the shape, center, and variability of the probability distribution of T. Study habits Study habits are so important that Mrs. Irvine often considers implementing her own study at MNHS. Fortunately, the Survey of Study Habits and Attitudes is a psychological test that exists already. This test measures academic motivation and study habits_ The SSHA score F on a randomly selected female student at a large university has mean 120 and standard deviation 28, and the SSHA score M of a randomly selected male student at the university has mean 105 and…

Prehistoric pottery vessels are usually found as sherds (broken pieces) and are carefully reconstructed if enough sherds can be found. Information taken from a study provides data relating x = body diameter in centimeters and y = height in centimeters of prehistoric vessels reconstructed from sherds found at a prehistoric site. The following Minitab printout provides an analysis of the data. Predictor Coef SE Coef T P Constant -0.233 2.429 -0.09 0.929 Diameter 0.7948 0.1671 5.33 0.001 S = 4.10980 R-Sq = 80.3%       (a) The standard error Se of the linear regression model is given in the printout as "S." What is the value of Se?   (b) The standard error of the coefficient of the predictor variable is found under "SE Coef." Recall that the standard error for b is  Se   Σx2 −  1 n (Σx)2 .  From the Minitab display, what is the value of the standard error for the slope b?
