Adam tabulated the values for the average speed on each day of his road trip as 60.5, 63.2, 54.7, 51.6, 72.3, 70.7, 67.2, and 65.4 mph. If Adam wanted to construct a one-sample t-statistic, what would the value for the degrees of freedom be? 4 7 9 8 RATIONALE The degrees of freedom for a 1 sample t-test are df=n-1 where n is the sample size. In this case, n=8, then df = n-1 = 8-1 = 7. CONCEPT T-Tests 2 9/18/2020 Sophia :: Welcome Steven measures the weight of a rando...

Mike tabulated the following values for heights in inches of seven of his friends: 65, 71, 74, 61, 66, 70, and 72. The sample standard deviation is 4.577. Select the 95% confidence interval for Mike's set of data. 59.95 to 76.91 59.95 to 72.67 64.19 to 76.91 64.19 to 72.67 RATIONALE In order to get the 95% CI , we first need to find the critical t-score. Using a t-table, we need to find (n-1) degrees of freedom, or (7-1) = 6 df and the corresponding CI. Using the 95% CI in t...

A researcher has a table of data with four column variables and three row variables. The value for the degrees of freedom in order to calculate the statistic is __________. 12 6 3 11 RATIONALE Recall to get the degrees of freedom we use df = (r-1)(c-1) where c and r are the number of rows and columns. This means df = (4-1)(3-1) = 3*2 =6. CONCEPT Chi-Square Test for Association and Independence 2 7/2/2020 Sophia :: Welcome What value of z* should be used to construct a...

RATIONALE Using the z-chart to construct a 97% CI, this means that there is 1.5% for each tail. The lower tail would be at 0.015 and the upper tail would be at (1 - 0.015) or 0.985. The value of 0.9850 is actually on the z-table exactly. 0.9850 corresponds with a z-score of 2.17. CONCEPT Confidence Intervals 2 George measured the weight of a random sample of 49 cartons of apples. The mean weight was 45.5 pounds, with a standard deviation of 3. To see if the cartons have a significant...

How many feet is this equivalent to? • 5,280 feet • 16,368 feet • 4,989 feet • 15,840 feet RATIONALE In general, we use conversion factors to convert from one unit to another. A conversion factor is a fraction with equal quantities in the numerator and denomi...
