z=1.76
Assuming that alternative hypothesis is 2 sided
P value=2*P(Z>z)=2*P(Z>1.76)=0.0784
We can reject it at a=0.10 as p value is less than 0.10 but we can't reject it at 0.05
hence answer is
a) a=0.10 but not at a=0.05
If z=1.76, Ho Can be rejected at _____. A) a=.10, but not at a=.05. B) a=.05...
If z = 1.67, H0 can be rejected at ______________. α = .01 and α = .05 α = .05 and α = .10 α = .10, but not at α = .05 α = .05, but not at α = .10
11. If the null hypothesis is rejected at a 05 significance level, it (a) must also be rejected at a.10 significance level. (b) might also be rejected at a .10 significance level. (c) must not be rejected at a.10 significance level. (d) none of the above lfte null hypothesis İs not rejected at a .05 significance level, it: (a) will also not be rejected at a.01 significance level. (b) might be rejected at a .01 significance level. (e) will be...
If p-value is 0.11 the null hypothesis can be rejected at a = .05. the null hypothesis can be rejected at a =.10. the null hypothesis can be rejected at a =.01. none of the above. 问题8 19 The test statistic for testing significance of the one regression coefficient follows Normal Distribution.

3) 3) A company claims that 9 out of 10 doctors (i.e., 90%) recommend its brand of cough syrup to their patients. To test this claim against the alternative that the actual proportion is less than 90%, a random sample of doctors was taken. Suppose the test statistic is z .-2.23. Can we conclude that Ho should be rejected at the a) a = .10, b) a = .05, and c) a - .01 level? A) a) yes; b) yes;...
For each give (a) the Z-Score cutoff (or cutoffs) on the comparison distribution at which the Null Hypothesis should be rejected, (b) the Z-score on the comparison distribution for the sample score, and (c) your conclusion.
