Let assume that  x ̅ ~ N (50, 2) and x ~ N (50, 20), what is the sample size?  Assume that x represents some population.   A. 100   B. 20   C. 200   D. 50

what is the median numebr of touchdowns

The data shown to the right are from independent simple random samples from three populations. Use these data to complete parts (a) through (d). Sample 1| Sample 2| Sample 30 E Click the icon to view a table of values of Fa- 4 5 2 6 14 a. Compute ST, SSTR, and SE using the following computing formulas, where x, is the ith observation, n is the total number of observations, n; is the sample size for population j, and T; is the sum of the sample data from population j. SST = Ex? - (Ex)? /n, SSTR= E(T? /n) - (Ex)? /n, and SSE = SST-SSTR Compute the values required to find SST, SSTR, and SSE. n= Ex = Ex = E(T; /n) = (Type integers or decimals. Do not round.) Calculate SST, SSTR, and SSE using the computing formulas. SST = (Type an integer or a decimal. Do not round.) SSTR= (Type an integer or a decimal. Do not round.) SSE = (Type an integer or a decimal. Do not round.) b. Compare your results in part (a) for SSTR and SSE with the following results from the defining formulas. SSTR = En (x…

The instructor takes a random sample of size from the population data and obtains the following sample data: x 405 385 495 385 555 470   5 If we take random samples of size n = 6 from this population, the number of possible samples is: a 11,481,019,312               b 11,367,345,853               c 11,254,797,874               d 11,143,364,232
