1. How do sampling distribution, population mean, sample mean, variability, sample size, and probability all relate to each other 2. How do probability, Type I Error, null hypothesis, and alpha all relate to each other
Attempts:Keep the Highests 4. Sample size, statistical significance, and practical importance Cities across the country are passing higher minimum wages, increasing the discrepancy between the wages in the dity and those in the suburbs. Suppose you are interested in the relationship between unemployment duration in the city and the surrounding suburbs in areas where the dites have minimum wages that are at least $3 higher than the minimum wages of the surrounding suburbs. The results are shown in the following...
Define: mean, median, mode, variability, correlation, positive correlation, negative correlation, statistical significance
Assume that you have a sample size of n1 = 16 with a mean of 42 and a standard deviation (S) equal to 9. Assume that you have another independent sample with n2 = 25, a mean of 36 and a standard deviation (S) of 4. Assume you are directed to use a significance level of α = 0.01. [DM.4] Construct the appropriate hypothesis test. Identify H0 and H1. What are the appropriate critical values? (4 Decimal Places) From what...

A sample mean, sample size, and sample standard deviation are provided below. Use the one-mean t-test to perform the required hypothesis test at the 1% significance level. x=22 s=6 n=15 H0: M=24 Ha: M<24 The test statistic is t=
How can you decrease the variability in a sample poll? A. Increase the sample size B. Decrease the sample size C. Increase the bias D. Decrease the bias E. None of the above
Discuss the difference between correlation and causation and the difference between statistical and practical significance. Please give examples of each to help define each concept.
