To determine whether children (considered as group 1) prefer warmer room temperature than adults (considered as group 2), a sample of data from 10 adults and 10 children were collected. If the test statistic is 3.02. What is the p-value

0.0013

Step-by-step explanation:

Given:

Sample size for children, n1 = 10

Sample size for adults, n2 = 10

Test statistics, Z = 3.02

Required:

Find the p-value

P-value also called probability value is the probability of obtaining results which supports the null hypothesis, H0.

To find the p-value, we use:

P-value = P(Z > 3.02)

P-value = 1 - P(Z < 3.02)

Using the standard normal table, we have:

NORMSTD(3.02) = 0.9987

Therefore,

P-value = 1 - 0.9987

P-value = 0.0013

Thus, the pvalue is 0.0013

what are the answear choices to the question.
