A sample of 9 data yields the following results: sample mean is 4 and sample variance is 3. For unknown reasons, two of the sample values are lost and when redoing the accounts with the remaining data, a new sample mean of 4 is obtained. and a new sample variance of 3/2. a. Lost data has other values. b. The missing data is 2 and 6. c. The missing data is 0 and 8. d. The missing data is 4...

Using a two-tailed one-sample z-test from a sample of size n, a researcher rejects the null hypothesis as z = 2.0 is greater than the critical value 1.96 at α = .05. What does this mean? Choose ALL the correct options from the following. a. As α = .05, the probability that the null hypothesis is correct is less than 5% b. As α = .05, the probability that the alternative / research hypothesis is correct is more than 95%...

A sample size 20 yields a sample mean of 23.5 and a sample standard deviation of 4.3. Test H0: Mean ≥ 25 at (x = 0.10. HA: Mean < 25. This is a one-tailed test with lower reject region bounded by a negative critical value. Pvalue 0.932. H0 not rejected. Conclude mean > or equal to 25 plausible Pvalue 0.135. H0 not rejected. Conclude mean ≥ 25 plausible Pvalue 0.068. H0 not rejected. Conclude mean< 25 Noe of these answers...
