Calculate the statistic, set up the rejection region, interpret the result, and draw the sampling distribution.

i)
H0: µ=10 H1: µ≠10 Given that: σ=10, n=100, X =13, α=0.05.

H0: µ=50 H1: µ<50 Given that: σ=15, n=100, X =48, α=0.05.

ii)

Part b)
H0: µ=10 H1: µ≠10 Given that: σ=10, n=100, X =13, α=0.05.

H0: µ=50 H1: µ<50 Given that: σ=15, n=100, X =48, α=0.05.
A statistics practitioner is in the process of testing to determine whether is enough evidence to infer that the population mean is different from 180. She calculated the mean and standard deviation of a sample of 200 observations as X =175 and s=22.

please show all the necessary steps and no short cuts.

thank you

A) A test statistic value of 2.14 puts it in the rejection region. If the test statistic is actually 2.19 then we know the p-value is less than the significance level for the test. True or false? Explain. B) The null hypotheses is false. The p-value is less than the significance level. Do we have a type 1 error, a Type 2 error, or a correct decision. Give an explanation. C) For a right tailed test a test statistic of...

1-6:True or False? 1) The sampling distribution of a statistic is the distribution that is formed using the computed statistic from a every possible sample, only of a given size, taken from the population. 2) The mean of the sampling distribution of a sample mean equals the population mean divided by the square root of the sample size. 3) The standard deviation of the sampling distribution of a sample mean equals the population standard deviation divided by the square root...

1) state your hypotheses; 2) draw a graph showing the critical z-scores and the rejection region; 3) calculate z-obtained; 4) make a conclusion. Does regular exercise improve cognitive skills? A sample of 67 3rd grade students was randomly assigned into 2 groups. One group (N=32) participated in an afterschool fitness program 3 days a week. Another group (N = 35) attended a regular afterschool care program. After 3 months, the mean cognitive test score in the first group was 138...
