Question

With *H*_{a} : μ ≠ 151

you obtain a test statistic of z=1.54. Find the p-value accurate to
4 decimal places.

p-value =

Please provide a step-by-step for a TI-84 calculator.

Answer #1

*H*_{a} : μ ≠ 151

z=1.54

Using following steps you can get P- Value over TI-84.

1. Press button 2nd

2.Press button VARS (DISTR)

3.Scroll down to normalcdf(

4.Press button ENTER

5.Now enter values as given

Lower : 154

Upper: 9999

: 0

: 1

6. Now Press button Enter

Now you will see Syntax normalcdf(1.54, 9999, 0, 1)

7.Press button ENTER

8.Now you will get P-Value for one tail (Right tail) as follows.

0.0617801925

9.but we want for two tail so just multiply result by 2

0.0617801925 * 2 = 0.123560385

Thus we get,

**P-Value = 0.1236**

Assume that z is the test statistic.
(a) H0: μ = 22.5,
Ha: μ > 22.5; x = 25.8,
σ = 7.8, n = 29
(i) Calculate the test statistic z. (Round your answer to
two decimal places.)
(ii) Calculate the p-value. (Round your answer to four
decimal places.)
(b) H0: μ = 200,
Ha: μ < 200; x = 191.1,
σ = 30, n = 24
(i) Calculate the test statistic z. (Round your answer to
two decimal places.)...
