Consider the following hypothesis test: h 0: 20 h a: < 20 a sample of 50 provided a sample mean of 19.4. the population standard deviation is 2. a. compute the value of the test statistic (to 2 decimals). if your answer is negative, use minus "-" sign b. what is the p-value (to 3 decimals)

p-value is 0.016.

Step-by-step explanation:

Since we have given that

Sample mean = 19.4

Sample size n = 50

Standard deviation = 2

We need to find the test statistic value which is given by

p-value is given by

Hence, p-value is 0.016.
