weatherwise is a magazine published by the American Meteorological Society. One issue gives a rating system used to classify Nor'easter storms that frequently hit New England and can cause much damage near the ocean. A severe storm has an average peak wave height of ? = 16.4 feet for waves hitting the shore. Suppose that a Nor'easter is in progress at the severe storm class rating. Peak wave heights are usually measured from land (using binoculars) off fixed cement piers. Suppose that a reading of 36 waves showed an average wave height of x = 16.9 feet. Previous studies of severe storms indicate that ? = 3.5 feet. Does this information suggest that the storm is (perhaps temporarily) increasing above the severe rating? Use ? = 0.01. What is the value of the sample test statistic? Round two decimal places.
To compute a student's Grade Point Average (GPA) for a term, the student's grades for each course are weighted by the number of credits for the course.

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury (mmHg), for a sample of 10 adults. The following table presents the results. Use a TI-84 calculator to answer the following. Diastolic Systolic Diastolic Systolic 134 87 118 115 130 76 113 77 116 70 123 77 133 91 119 69 112 75 Based on results published in the Journal of Human Hypertension Send data to Excel If the systolic pressures of two patients differ by 16 millimeters, by how much would you predict their diastolic pressures to differ?

John Kittle, an independent insurance agent, uses a five-year moving average to forecast the number of claims made in a single year for one of the large insurance companies he sells for. He has just discovered that a clerk in his employ incorrectly entered the number of claims made four years ago as 1,400 when it should have been 1,200.a. What adjustment should Mr. Kittle make in next year’s forecast to take into account the corrected value of the number of claims four years ago?b. Suppose that Mr. Kittle used simple exponential smoothing with a = .2instead of moving averages to determine his forecast. What adjustment is now required in next year’s forecast? (Note that you do not need to know the value of the forecast for next year in order to solve this problem.)

NarStor, a computer disk drive manufacturer, claims that the average time to failure for its hard drives is 14,400 hours. You work for a consumer group that has decided to examine this claim. Technicians ran 16 drives continuously for three years. Recently the last drive failed. The time to failure (in hours) are given below.

Copy the data to Desmos to draw a scatterplot of the data. Make sure to adjust the years so they represent years after 1980. a) Is it better to model the data with a linear or with an exponential model? Select an answer b) Use regression in Desmos to find an appropriate model for f. Make sure to check Log mode in the parameter window in Desmos if you are fitting an exponential model. f(t) places. Round the coefficients to 4 decimal Hint: Use the variable t from the drop down menu when entering the equation. Do not just type in t. c) Predict the number of polio cases in 2019. d) Find the approximate half-life of the number of polio cases. Round the answer to one decimal place. years

Twenty five right-handed students were asked to turn a knob (using their right hands) that moved an indicator by screw action. There were two identical instruments, one with a right-hand thread (the knob turns clockwise) and the other with a left-hand thread (the knob turns counterclockwise). The data presented below gives the times (in seconds) each subject took to move the indicator a fixed distance: Obs.# R Obs.# R L L Obs.# R 1 113 8 116 166 22 100 2 105 105 9 75 146 23 89 3 130 133 10 96 123 24 85 4 101 108 11 122 135 25 88 5 138 115 12 103 6 118 170 13 116 7 87 103 14 107 At 1% level of significance, can we conclude that these right-handed students found it easier to use the knobs with a right-hand thread? Use the following form of the difference: right-left. 1. Test Stat: L 137 2. Critical Region: a. T> 2.492 b. Tabs (2.492) c. T> abs (-2.492) d.
