Use the sample from Topic 2 DQ 1 and test that the population mean for rolling a single die is 3.5.
Here is topic 2 Dq 1 : these are the numbers I got when I rolled a single die 50 times. I got a dat set of :2,2,5,4,4,5,6,4,4,2,4,6,3,1,5,5,1,5,3,5,4,2,4,2,5,1,5,5,6,1,2,3,1,6,1,4,2,6,3,2,5,5,5,6,1,6,1,1,4
My Mean was:3.62 My Mode was:5 My Median was:4 My Standard Deviation was:1.772 My variance was:3.138

Use the sample from Tooic 2 DQ 1 and test that the population mean for rolling a singke die is 3.5. Null hupothesis- population mean equals 3.5 Alternative hypothesis- population mean can not equal 3.5. Results for Rolling die 50 times: 1,3,2,6,3,4,4,4,2,3,1,1,5,1,4,6,5,5,1,2,4,3,1,4,5,5,5,2,5,3,1,3,2,4,2,5,5,2,4,4,6,5,3,2,4,2,4,6,1,2 Mean: 3.34 Mode: 4 Median: 3.5 Standard Deviation: 1.634 Variance: 2.632

1. Select all true statements about sample mean and sample median. A) When the population distribution is skewed, sample mean is biased but sample median is an unbiased estimator of population mean. B) When the population distribution is symmetric, both mean and sample median are unbiased estimators of population mean. C) Sampling distribution of sample mean has a smaller standard error than sample median when population distribution is normal. D) Both mean and median are unbiased estimators of population mean...

If I had a normal population, and I went out and got bunch of sample pairs (lets pretend it was a thousand)... If were to do an F test for an variance eqaulity... and lets say I wanted a 95% confidence... how many times do I expect to reject my null? I'm not sure how I would go about this? How would i know with out actual data to plug into my numbers?

A sample mean, sample size, and population standard deviation are provided below. Use the one-mean z-test to perform the required hypothesis test at the 10% significance level. x=37, n = 31, σ=9, H0 : μ=39, Ha: μ<39 EB Click here to view a partial table of areas under the standard normal curve. The test statistic is z- (Round to two decimal places as needed.)

1. Generating the sampling distribution of the mean Аа Аа Suppose you use sampling techniques to estimate the mean of the numbers 1, 2, 3, 4, 5, 6, 7, and 8. To do this, you perform an experiment in which you roll an eight-sided die two times (or equivalently, roll two eight-sided dice one time) and calculate the mean of your sample The true mean (u) of the numbers 1, 2, 3, 4, 5, 6, 7, and 8 is and...
