Here sample 10 people in a high school to try to predict GPA in 10th grade from GPA in 9th grade. here determine that SSE = 5.8.  Compute the standard error of the estimate?

Use the formula to find the standard error of the distribution of differences in sample means, ₁ - X₂. Samples of size 105 from Population 1 with mean 86 and standard deviation 13 and samples of size 80 from Population 2 with mean 73 and standard deviation 16 Round your answer for the standard error to two decimal places. standard error =

Pyramid Lake is on the Palute Indian Reservation in Nevada. The lake is famous for cutthroat trout. Suppose a tells you that the average length of trout caught in Pyramid Lake Is mu = 19 Inches. Howevera survey reported that of a random sample of 46 fish caught, the mean length was overline x =18.6 lnch , with estimated standard s = 2.7 inches. these data Indicate that the average length of a trout caught in Pyramid Lake less than mu = 19 inches? Use a=0.05 Please answer ONLY parts D & E

Miswrote P(x) 0.041 for 0.141, which changes the mean to 1.5.

The biologist wants to estimate the average age of Coyotes in Tuolumne County. Her estimates from past experience suggest the standard deviation is 1.3 years. How big of a sample should she take to be 95% sure his estimate is off by no more than 3minutes?

Use the formula to find the standard error of the distribution of differences in sample means, x¯1-x¯2.Samples of size 115 from Population 1 with mean 94 and standard deviation 14 and samples of size 85 from Population 2 with mean 75 and standard deviation 17Round your answer for the standard error to two decimal places.standard error = Enter your answer in accordance to the question statement

In a measurement of B two results were obtained, B1 = (8.3+/- 0.78) mT and B2 = (8.81+/- 0.20) mT . The error on the weighted/arithmetic mean is (Report your answer in mT with 3 significant figures)

The trunk diameter, in centimeters,  of a certain variety of pine tree is represented by X~N(150, 30).  What is the 75th percentile of trunk diameters?  Round to two decimal places.

A population of score has μ  = 44. in this population, a score of X = 40 corresponds to z = -0.50. What is the population standard deviation?
