Consider the following competing hypotheses and accompanying sample data drawn independently from normally distributed populations. (You may find it useful to reference the appropriate table: z table or ttable) Ho: H1 H2 = 0 HA: H1 H20 X1 = 65 01 = 14.10 n1 = 19 2X2 = 74 Test statistic 02 = 1.57 n2 = 19 a-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.)

Consider the following hypothesis test. The null hypothesis is "The mean body temperature for humans is 98.6 degrees Farenheit." and the alternative hypothesis is "The mean body temperature for humans differs from 98.6 degrees Farenheit." Answer the following questions. a. "The mean body temperature for humans in fact differs from 98.6 degrees Farenheit and the result of the sampling lead to that conclusion" is aA. 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. Type II errorB. Type I errorC. correct decision c. "The mean body temperature for humans in fact is 98.6 degrees Farenheit and the result of the sampling do not lead to the rejection of the fact that the mean body temprature is 98.6 degrees Farenheit" is aA. Type I errorB. correct decisionC. Type II error d. "The mean…

Below is the question I am having a problem with as well as the portion of the answer I have come up with. I do not know if I am right or not, but I need an explanation to understand this, please.    What information does the F ratio on the SPSS output for an independent sample T test provide?  That is, what assumption does it test. A researcher might use the independent sample t test when he assumes that there will be equal mean populations between to variances.              To calculate the independent sample t test, one would use this formula: t = m1-m2                                                                                                                                          SEm1-m2
