Choose the correct option from those given below.What is the standard deviation of a large sample size?Standard deviation = (sample standard deviation/sample size)Standard deviation = (sample standard deviation/sqrt(sample size))Standard deviation = (Sample standard deviation/(sample size)^2)Standard deviation = (Sample standard deviation/mean of sample size)

Which of the following is used when calculating the sample standard deviation? Check all that apply.Sample SizeModeMedianMeanRange

29.The standard deviation of the sample means is equal to which of the following?  A. population standard deviation divided by the square root of n (sample size)  B. sample standard deviation divided by n (sample size)  C. sample standard deviation divided by the square root of n (sample size)  D. population standard deviation divided by n (sample size)

A normal population has mean 100 and variance 25.How large must the random sample be if you want the standard error of the sample average to be 1.5?a.9b.10c.11d.None of the otherse.12

If the standard deviation of the population which is normally distributed is 50 and the sample size is 16 then the standard deviation of the sampling distribution is*11.512.514.513.5

A population's standard deviation is 12. We want to estimate the population mean with a margin of error of 2, with a 95% level of confidence. (Use t Distribution Table & z Distribution Table.)How large a sample is required? (Round your intermediate calculations to 2 decimal places and round up your answer to the next whole number.)
