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.

One Sample t test: N Independent Samples t test: N-1 c. One Sample t test: N-1 Independent Samples t test: N-2 d. One Sample t test: N-2 Independent Samples t test: N-1List the elements of each of the following sample space. the set S = {x | 2x - 4 > 0,X < 1}.A subset of a population selected to represent the population is a subset O sample small population None of the alternative answers is correct.
- Which of the following ensures a sample is representative of its population? The sample is convenient. The sample has properties that are matched to those in the population. The sample is the same size as the population. The sample is unique.The Sampling Frame is the set of all people you wish to sample from and each sample will select different people and yield different values, known as Sampling Variability. Group of answer choices True FalseRequlred Information Three components are randomly sampled, one at a time, from a large lot. As each component is selected, It Is tested. If it passes the test, a success (S) occurs; If It falls the test, a fallure (F) occurs. Assume that 77% of the components In the lot will succeed in passing the test. Let X represent the number of successes among the three sampled components. Let Y represent the number of successes if four components are sampled. Find PY= 3). Numeric Response 0.4565

P(E4)= (Simplify your answer.) b. The odds in favor of E4 occurring, in lowest terms, are (Type whole numbers.) The odds against E4, in lowest terms, are (Type whole numbers.)A coin is tossed three times, the result being either Heads or Tails. Let X represent the number of heads obtained in the three tosses.
