The t test for the mean difference between 2 related populations assumes that the  population sizes are equal.  sample variances are equal.  population of differences is approximately normal or sample sizes are large enough.  All of the above.

You are conducting a study to see if the proportion of voters who prefer candidates a is significantly different from 0.6. Thus you are performing a two-tailed test. Your sample data produce the test statistics z=-1.65. Find the p-value accurate to 4 decimal places

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?

Two separate samples, each with n = 14 individuals, receive different treatments. After treatment, the first sample has SS = 1316 and the second has SS = 1620. Find the pooled Variance for two independent samples. (hundredths place) Type only the pooled variance.

A sample of n=4 scores has ΣX=8 and ΣX2=40. What is the value of the sample variance, s2?​

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

When computing the variance using a sample of size n = 30, we divide the sum of squared deviations by Give your answer as a whole number.

a sample of n = 10 score has ss= 108 what is the variance for this sample

The mean square error is the variance plus the bias. True O False
