Consider testing H0: p=0.1 versus H1: p<0.1. If the standardized critical value is -1.00 (i.e. the standardized rejection region is from negative infinity to -1.00) then what was the selected significance level (alpha)? (Answer as a probability, not a percent. Record your answer accurate to at least the nearest THIRD decimal place with standard rounding.)

Given hypothesis testing problem is: H0: p=0.1 versus H1: p<0.1
zcrit=-1.00
The level of significance is the probability of rejecting null hypothesis when it is true.
That is:
### By using z table.
That is:

In hypothesis testing, does choosing between the critical value method or the P-value method affect your conclusion? Explain. Choose the correct answer below O A. No, because both methods involve comparing the standardized test statistic with the rejection region(s). O B. No, because both involve comparing the test statistic's probability with the level of significance. ○ C. Yes, because the P-value method is more accurate than the critical value method. O D. Yes, because the crtical value method uses critical...

Consider two independent samples: Sample 1 has 217 observations and Sample 2 has 440 observations. In testing H0: (mu2 - mu1) = 0 versus H1: (mu2 - mu1) LaTeX: \ne≠ 0, a t test statistic of -3.111 with 400 degrees of freedom are correctly computed. What is the P-value? (Answer as a probability, not a percent. Record your answer accurate to at least the nearest third decimal place with standard rounding.) .
