HI group, I was wondering if someone can check my answers to see if I'm right on the following questions. Thanks!
Alex
1.) The 95% confidence interval states that 95% of the sample means of a specified sample size selected from a population will lie within plus and minus 1.96 standard deviations of the hypothesized population mean.
a.) True
b.) False
My answer: False (population mean lies within the interval)
2.) If the null hypothesis that two means are equal is true, where will 97% of the computed z- values lie between?
a.) +- 2.58
b.) +- 2.33
c.) +- 2.17
d.) +- 2.07
e.) none of the above.
My answer: e : none of the above
3.) If the confidence interval includes 0, there is no difference in the pair of treatment means.
a.) Ture
b.) False
My answer: False
