Which of the following samples will have the smallest value for the estimated standard error?​ Group of answer choices ​n = 16 with s2 = 64 ​n = 4 with s2 = 64 ​n = 4 with s2 = 16 ​n = 16 with s2 = 16

One sample has n=7 and SS=35 and a second sample has n =17 and SS =45. What is the pooled variance for these two samples?

Got stuck, and wasn’t sure what to do.

What are the values for SS and variance for the following sample of n = 3 scores? Sample:  8, 5, 2

A researcher takes sample temperatures in Fahrenheit of 20 days from Minneapolis and 18 days from Cleveland. Use the sample data shown in the table. Test the claim that the mean temperature in Minneapolis is different than the mean temperature in Cleveland. Use a significance level of α=0.01. Assume the populations are approximately normally distributed with unequal variances.Note that list 1 is longer than list 2, so these are 2 independent samples, not matched pairs.   Minneapolis Cleveland 70.1 66.1 69.5 65.9 65.7 61 71.7 62.8 62 67.9 75.3 74.5 63.2 69.1 62 72.5 76.9 80.4 71.3 72.7 70.9 70.4 70.5 76.6 65.1 62.2 76.2 66.1 70.3 86 69.5 81 80.2 68.3 74.3 63.3 70.7   64.6     The Null Hypotheses is: H0: μ1 - μ2 = 0 What is the alterative hypothesis?
