Answer #1

Distribution Plot Distribution Plot Normal, Mean-0, StDev-1 0.4 0.3 0.2 0.1 α:01 0.0 1.282 0

-------------------------------------------------------------------------------------------------------------------------------------------------------

Interpretation:

The above normal probability distribution plot enables that the critical value of the left-tailed test is $30.10一一1.282$ The level of significance is $α = 0.10.$ The standard normal distribution is with mean is $μ=0$ and the standard deviation is $sigma =1.$
