Find the mean hourly cost when the cell phone described above is used for 240 minutes.
The means and standard deviations are given in the data table. With a correlation of 0.826, calculate the slope and explain what the slope tell you in the context of this problem. Calculate the intercept and explain what the intercept tell you in the context of this problem. For the individual with dose = 2.02, what is the predicted AZT concentration and what is the residual?
1. What is the value of the slope of the best fit trends line for the relationship between TDD and the depth of the active layer. 2. If α = 0.05, is this slope statistically significant? (yes/no) 3. Compute a new variable that states the depth of the active layer in inches. The conversion formula is: (depth in inches) = (depth in centimetres) / 2.54 What is the mean depth of the active layer, measured in inches?
Old Faithful is a geyser located in Yellowstone National Park, WY. It may not be surprising that there is a correlation between the amount of time you have to weight between eruptions and the eruption length. You can witness eruptions that last up to 5 minutes but you may have to wait up to 90 minutes for them to occur whereas 2 minute eruptions tend to have about an hour wait-time. The following is a scatter-plot of 272 Old Faithful eruptions the x-variable is eruption length and the y-variable is waiting time. The equation for the best fit line is also listed on the graph. Does the eruption with the shortest eruption length also have the shortest waittime? Is the correlation between eruption length and waiting time positive or negative? Guess the correlation coefficient. Using the the equation for the best fit line, predict the waiting time for an eruption that lasts 3.4 minutes. Using this data would you feel comfortable making a prediction for the wait time of an eruption that…
A forester measured the trees in a large woods up for sale. He concluded that the diameter of the trees was normally distributed with mean 12.4 inches and standard deviation 4.7 inches. Which of the following equations can be used to find the diameter x which is at the 90th percentile? (A) 0.90= (B) 1.28 = x-12.4 (4.7)² x 12.4 (4.7)² x-12.4 (C) 0.90= 4.7 x-12.4 (D) 1.28= 4.7 (E) 1.645= x-12.4 4.7
Consider a certain data set on shoulder girth and height of a group of individuals. The mean shoulder girth is 107.20 cm with a standard deviation of 10.37 cm. The mean height is 171.14 cm with a standard deviation of 9.41 cm. The correlation between height and shoulder girth is 0.67. Write the equation of the regression line for predicting height.
• In a political science class, the teacher gives a midterm exam and a final. The association between midterm and final scores is linear. The summary statistics are shown below. Midterm Mean=75, Midterm Standard Deviation=10 Final Mean=75, Final Standard Deviation=10 r=0.8 According to the regression equation, for a student who gets 85 on the midterm (one standard deviation above average) what is the predicted final exam grade? 83 85 70 75
Suppose the linear relationship between traffic violations and auto insurance premium has SSR of 2825 and SST of 3150. What percent of the insurance premium is unexplained by traffic violation?
Suppose that you wish to estimate the difference between mean pH measurements of rainfalls in two different locations, one in relatively unpolluted area and the other in an area subject to heavy air pollution. You want to be 95% confident that the margin of error for the difference between mean pH of rainfalls in relatively unpolluted area and mean pH of rainfalls in an area subject to heavy air pollution will not exceed 0.1 pH. How many rainfalls (pH measurements) must be included in each sample? Assume that the variance of pH measurements in a relatively unpolluted area is equal to 2 = 20, and the variance of pH measurements in an area subject to heavy pollution is equal to 2 = 0.25, and samples will be of equal size (n = n₂ = n). 2 It is supposed that values of pH in rainfalls are normally distributed in polluted and unpolluted areas. The number of rainfalls (pH measurements) that must be included in each sample is

Biological oxygen demand (BOD) is a pollution index that is monitored in the treated effluent of paper mills. A certain paper mill has taken 31 samples over the past 3 months. The mean and standard deviation for the sample data are 3.42 and 0.728 ppm respectively. The mill would like to see if this sample indicates that the true average BOD in their treated effluent exceeds the targeted 3.00 ppm. Let ? = 0.05. A) The test statistic, (ttest), for this data set is: Note: Round your answer to the nearest hundredth.B) The p-value is: C) The statistical decision and corresponding English interpretation for this study are: Fail to reject Ha: conclude that the true BOD in treated effluent exceeds 3 ppmFail to reject Ho: we cannot conclude that the true BOD in treated effluent exceeds 3 ppm Reject Ha: we cannot conclude that the true BOD in treated effluent exceeds 3 ppmReject Ho: conclude that the true BOD in treated effluent exceeds 3 ppm
