  1. A local trucking company fitted a regression to relate the travel time (days) of its shipments as a function of the distance traveled (miles). The fitted regression is Time = −7.126 + 0.0214 Distance, based on a sample of 20 shipments. The estimated standard error of the slope is 0.0053. In a two-tailed test for zero slope at
0 0
Answer #1

1)

Ho:   ß = 0
Ha:   ß ╪ 0

estimated slope=   0.0214
std error =    0.0053

t-test statistic =    t = estimated slope / std error = 0.0214/0.0053 = 4.04

so, answer is option d)4.04

    Question 13 (1 point) A trucking company considered a multiple regression model for relating the dependent variable of total daily travel time for one of its drivers (hours) to the predictors distance traveled (miles) and the number of deliveries of made. After taking a random sample, a multiple regression was performed and the output is given below. Interpret the slope of the distance variable. Question 13 options: 1) When distance increases by 1 miles, time decreases by 1.18 hours, holding...

    Bardi Trucking Co., located in Cleveland, Ohio, makes deliveries in the Great Lakes region, the Southeast, and the Northeast. Jim Bardi, the president, is studying the relationship between the distance a shipment must travel and the length of time, in days, it takes the shipment to arrive at its destination. To investigate, Mr. Bardi selected a random sample of 20 shipments made last month. Shipping distance is the independent variable and shipping time is the dependent variable. The results are...

    The maintenance manager at a trucking company wants to build a regression model to forecast the time (in years) until the first engine overhaul based on four explanatory variables: (1) annual miles driven (in 1,000s of miles), (2) average load weight (in tons), (3) average driving speed (in mph), and (4) oil change interval (in 1,000s of miles). Based on driver logs and onboard computers, data have been obtained for a sample of 25 trucks. A portion of the data...

    Calculate the average round-trip travel distance and travel time for each zone. Assume that people in Zone 0 have a travel distance and time of zero. Every other zone has increasing travel time and distance. Next, using average cost per mile and per hour of travel time, calculate the travel cost per trip. A standard cost per mile for operating an automobile is readily available from AAA or similar sources. Assume that cost per mile is $.30, or use the...

    Question 11: Cardiorespiratory fitness is widely recognized as a major component of overall physical well-being. Direct measurement of maximal oxygen uptake (VO2max) is the single best measure of such fitness, but direct measurement is time-consuming and expensive. It is therefore desirable to have a prediction equation for VO2max in terms of easily obtained quantities. A sample is taken and variables measured are age (years), time necessary to walk 1 mile (mins), and heart rate at the end of the walk...
