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.)

Answer #1

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:
