For each of the following situations, find the critical value(s) for z or t. a) H0:pequals0.9vs. HA:pnot equals0.9at alphaequals0.01

Step-by-step explanation:

Required: Find the critical value for z or t.

Null Hypothesis: P = 0.9

Alternative Hypothesis: P ≠ 0.9

α = 0.01   implies a confidence level of 99%

The critical probability by formula, is CP = 1 - (α/2)

CP = 1 - 0.01/2  = 0.995

Using 10 degrees of freedom on the table of percentage points of the t-distribution, the critical t-statistic corresponds to 3.17

.19875994384

step-by-step explanation:

1699/ 8548

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
