Child and Protective Services, a branch of the Department of Health and Human Services is investigating the monthly average number of children in foster care over the last several years. They are interested in seeing if the average is dropping from 235 children per month in 2001. The null hypothesis for this problem would be: Select an answer and submit.

Engineers concerned about a tower's stability have done extensive studies of its increasing tilt. Measurements of the lean of the tower over time provide much useful information. The following table gives measurements for the years 1975 to 1987. The variable "lean" represents the difference between where a point on the tower would be if the tower were straight and where it actually is. The data are coded as tenths of a millimeter in excess of 2.9 meters, so that the 1975 lean, which was 2.9647 meters, appears in the table as 647. Only the last two digits of the year were entered into the computer. 80 83 86 75 76 77 78 647 649 660 672 79 81 82 84 85 678 693 701 703 717 722 729 747 (a) Plot the data. Consider whether or not the trend in lean over time appears to be linear. (Do this on paper. Your instructor may ask you to turn in this graph.)

Based on data from 34 adults who exercise regularly, the line of best fit for the relationship between bicep girth (the length in centimeters around the upper arm) and the person's weight is: predicted weight = 2.6 bicep girth – 10.5 %3D where predicted weight is measured in kilograms and bicep girth is measured in centimeters.
Pesticide danger: One of the factors that determines the degree of risk a pesticide poses to human health is the rate at which a pesticide is absorbed into skin after contact. An important question is whether the amount in the skin continues to increase with the length of the contact, or whether it increases for only a short time before leveling off. To investigate this, measured amounts of a certain pesticide were applied to 20 samples of rat skin. Four skins were analyzed at each of the time intervals 1, 2, 4, 10, and 24 hours. The amounts of the chemical (in micrograms) that were in the skin are given in the following table.

According to an exit poll for an election, 55.1% of the sample size of 819 reported voting for a specific candidate. Is this enough evidence to predict who won? Test that the population proportion who voted for this candidate was 0.50 against the alternative that it differed from 0.50. Complete parts a through d below. OD. The parameter is the number of voters that voted for the candidate. Define the notation for the parameter. OA. p= the number of voters that did not vote for the candidate OB. p= the number of voters that voted for the candidate C. p=population proportion of voters that voted for the candidate D. p=sample proportion of votes for the candidate b. State the hypotheses and check the assumptions for a large-sample test. Choose the correct answer below. O A. Ho: p=0.50; H₂: p0.50 The assumptions for a large-sample test are met. c.

Question 1 Stopping Distances In a study on speed control, it was found that the main reasons for regulations were to make traffic flow more efficient and to minimize the risk of danger. An area that was focused on in the study was the distance required to completely stop a vehicle at various speeds. Use the following tables to answer the questions. MPH BRAKING DISTANCES (FEET) 20 20 30 45 40 81 50 133 60 205 80 411 Assume MPH is going to be used to predict stopping distance. Calculate the correlation coefficient ‘r’ for these values. What does a correlation coefficient tell about the relationship between two variables? Within what range can a correlation coefficient assume a value. Will you expect a positive, negative or zero correlation between the two variables for each of the following examples Variables Type of Correlation Grade of a student and hours spent studying Incomes and entertainment expenditures of…
