Answer 1

Answer #1

The appropriate test would be a Two-Sample t-test.

The hypothesis being tested is:

H₀: µ₁ = µ₂
H₁: µ₁ ≠ µ₂

This is a two-tailed test because we have to check if the two groups differ.

The SPSS output is:

Group Statistics Std. Error Mean VAR00002 VAR00001 1.00 2.00 N. 10 9 Mean 5.5900 4.4111 Std. Deviation .74154 1.03374 .23450

The p-value is 0.010.

Since the p-value (0.010) is less than the significance level, we can reject the null hypothesis.

Therefore, we can conclude that the two breeds differ.

Please give me a thumbs-up if this helps you out. Thank you!

To identify the correct Z(critical), it is important to determine whether the hypothesis test is one-tailed or two-tailed. The decision between a one- and two-tailed hypothesis is based on the researcher's expectations about the population from which the sample was selected.

You wonder whether the cohort currently in their mid-20s have had more sexual partners than older generations. Assume that the the average number of...

You have a sample size of N = 20. You will perform a one-tailed t-test with alpha = .05. You have looked up the critical value and it is -1.73. You have calculated t-test statistics of -1.41. Which of the following is correct? Reject the null or retain the null? You have a sample size of N = 37 and you are going to perform a one-sample t-test using alpha = .05. You go to the t-table and find that...

Run a one sample t-test for HGHTI_P to test if the CHIS sample is significantly different from 68(the average height in the U.S.). What can you conclude based on the results of your test (Hint: what does the p-value tell you?)? Do you reject the null hypothesis, or fail to reject the null hypothesis? Does the CHIS sample population have a statistically significant different average height than 68 inches tall?
