z = -1.66. The Z-statistic is calculated as follows. Here X signifies the obtained proportion. p stands for the mean proportion. The formula includes the standard error for the sample. From a total of 593 surveyed students, 64 met the criteria described. Thus, if the national percentage of binge drinkers is 13.1%, she has found the proportion in her data. The resulting z statistic for the dataset is derived accordingly.
Answer:
y hat = 2114.20 + 18.96x
Step-by-step explanation:
Given the least squares regression model equation:
y hat = -959.00 + 8.60x
weld diameter x; shear strength y (in pounds)
1 lb = 0.4536 kg
To convert shear strength y to kilograms:
y is multiplied by 0.4536
(y hat × 0.4536) = -959.00 + 8.60x
Divide both sides by 0.4536
(y hat × 0.4536) / 0.4536= (-959.00 + 8.60x) / 0.4536
y hat = 2114.1975 + 18.959435x
y hat = 2114.20 + 18.96x
Because the troop raised 10 times as much as Emily, multiply 950 by 10 to get 9500
The answer is found by dividing the total pages by the total time in minutes.
Calculating 7.5 divided by 9 equals approximately 0.8333, so Monica reads around 0.83 pages each minute on average.
