You may need to use the appropriate appendix table or technology to answer this question. The following results are for independent random samples taken from two populations. Sample 1 Sample 2 n1 = 20 n, = 30 X1 = 22.7 X2 = 20.1 s, = 2.3 2 = 4.6 (a) What is the point estimate of the difference between the two population means? (Use x, - x,.) 2.72 (b) What is the degrees of freedom for the t distribution? (Round your answer down to the nearest integer.) 48 (c) At 95% confidence, what is the margin of error? (Round your answer to one decimal place.) 1.9 (d) What is the 95% confidence interval for the difference between the two population means? (Use x, - Round your answers to one decimal place.) .6 to 4.4
A very small effect size can turn out to be statistically significant because the assumptions underlying the z test were too strict population standard deviations were too large deviation scores were used rather than raw scores the sample size was very large

Hello, can you please explain to me of this math problem. Break this math problem down for me to understand . Thank you. Use the standard normal distribution or the t- distribution to construct a 99% confidence interval for the population mean. Justifty your decision if neither distribution can be used explain. Why Intepret the results. In a recent season, the population standard deviation of the yards per carry for all running backs was 1.38. The yards per carry of 25 randomly selected running backs are shown below. Assume the yards per carry are normally distributed. 1.6, 4.8, 7.2, 4.5, 7.3, 7.3, 5.7, 2.6, 7.4, 1.9, 1.5, 4.3, 7.4, 3.9, 5.6, 3.3, 4.4, 3.5, 2.9, 4.3, 6.6, 2.7, 7.3, 6.9, 7.5 Which distribution should be used to construct the confidence interval? Use a normal distribution because σ is known and the data are normally distributed. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. (A). The 99% confidence interval…
Hi I am not undertanding this question very well can you please help me solve it question 3. Please write with eligible handwriting and if you use symbols make it clear which ones your using please. Thank you
Assuming variance > 1, which of the following must be true? The sample variance is calculated based on the sample size rather than the degrees of freedom The data are normally distributed Standard deviation < variance The model will explain more than 50% of the variance of the dependent variable
Could please help interpret this SPSS output of a Independent sample t-test?
