Two sample T test by hand, what do I do next? (n1 = 13 and n2 = 15)

sample mean 1: 2958.75

sample mean 2: 3361

variance 1: 261.05

variance 2: 334.20

tstat: -3.57

standard error: 112.64

t distribution: 25.75

These are the values I have so far, if someone could finish the t-test for me without using a software and explain I'd really appreciate it.

Expert Solution

Above problem is solved using two sample t test.

As hypothesis is not given, we have used two sided test.

Level of significance is not given so we assume it default value 0.05, alpha = 0.05

Here equal variance is assumed because 1st varince is not double of 2nd variance.

Dear student,

Consider the following sample information randomly selected from two populations. Sample 1 Sample 2 n1=100 n2=50 x1=30 x2=20 a. nbsp Determine if the sample sizes are large enough so that the sampling distribution for the difference between the sample proportions is approximately normally distributed. b. Calculate a 98% confidence interval for the difference between the two population proportions. a. Are the sample sizes sufficiently large? No, because np overbar and n(1minusp overbar) are less than 5 for both samples. No,...

I assert that the critical value of t, for a One sample t Test with a nondirectional alternative hypothesis and using a particular α level, will increase as sample size increases. Am I correct? Circle “YES” or “NO.” If NO, explain why not?

In a test for the difference between two proportions, the sample sizes were n1 = 120 and n2 = 85, and the numbers of events were x1 = 55 and x2 = 45. A test is made of the hypotheses H0: p1 = p2versus H1: p1 ≠ p2. Compute the value of the test statistic. Can you reject H0 at the α = 0.05 level of significance? Can you reject H0 at the α = 0.01 level of significance?
