With Ha : μ ≠ 151
you obtain a test statistic of z=1.54. Find the p-value accurate to 4 decimal places.
Please provide a step-by-step for a TI-84 calculator.
Ha : μ ≠ 151
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
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.
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
