z = 1.8 for Ha: µ > claimed value. What is the P-value for the test?
A. 0.9641
B. 3.59
C. 96.41
D. 0.0359
My answer is B ,NEED HELP PLEASEEE
To calculate the p-value for a hypothesis test, you need the test statistic and the appropriate distribution. In this case, since the alternative hypothesis is µ > claimed value, the test statistic is a z-score.
Given that z = 1.8, we need to find the p-value corresponding to this z-score.
To find the p-value, you can use a standard normal distribution table or a statistical calculator.
Using a standard normal distribution table:
1. Look up the absolute value of the z-score in the table, i.e., 1.8.
2. The closest value in the table is typically 1.8, since most tables provide values for up to two decimal places.
3. The corresponding p-value for 1.8 is 0.9641.
So, based on the standard normal distribution table, the p-value for the test is approximately 0.9641.
Therefore, the correct answer is A. 0.9641.
