Type I errorB. correct decisionC. Type II error b. "The mean body temperature for humans in fact is 98.6 degrees Farenheit but the result of the sampling lead to the conclusion that the mean body temprature for humans differ from 98.6 degrees Farenheit" is aA.

Many Americans believe that women talk more than men. A 1998 study tested this theory by evaluating the number of words spoken daily by men and women. The researcher of the study conducted a two-sample ?t‑test set at a signficance level of α=0.05. The null and alternative hypotheses, ?0 and ?1, are ?0:?M≥?W ?1:?M<?W where ?M represents the mean number of words spoken per day by men, and ?W represents the mean number of words spoken per day by women. The researcher randomly selected 20 men and 27 women and tracked the number of words spoken per day by each individual over a period of time. The sample results are summarized in the table. Population Samplesize Sample mean(words) Sample standarddeviation (words) Men ?M=20 x¯M=12867 ?M=8343 Women ?W= 27 x¯W=16496 ?W=7914 The population variances are unknown and assumed to be unequal. The Welch–Satterthwaite approximation of the degrees of freedom for this test is 39.8360. Assume the conditions for a two‑sample ?t‑test are…
