how to know that the confidence interval is 95 percent?

KK LEE on September 15, 2016 at 12:37 am

95% is just a sample. You can take any confidence level.

Sir, is it possible to reject H0 ? I calculated my X2 cal is 11.922, is it too big?

KK LEE on September 25, 2016 at 6:27 pm

Yes

Jia xin on October 1, 2016 at 1:25 am

May I know the test statistics is mean-mean(predicted height of short group)？or mean-mean(short group)

KK LEE on October 2, 2016 at 7:15 pm

Which test statistic do you mean

peipeichn on October 2, 2016 at 8:36 pm

sir, may i ask how to find the critical value at 8% of significance level?

KK LEE on October 2, 2016 at 9:15 pm

Which test are you referring?

vishnuphantom on October 7, 2016 at 5:56 pm

Sir, may I know how to ensure the randomness of the sample. (The Question in 1.a)

KK LEE on October 7, 2016 at 11:51 pm

Prepare a box with balls with numbers

Pick a ball
