Answer :
The p value of the data collected for the research paper is 0.23.
What is the p value?
The p value simply implies a number that is calculated from a statistical test which describes how likely one can find a particular set of observations when the null hypothesis is true.
From the information, the sample mean (x bar) was 101.5 kilometers, the population mean was 100.2 kilometers minutes, and the standard deviation was 7.6 kilometers.
The test statistic will be:
= (101.5 - 100.2) / (76 / ✓50)
= 13 / 1.0748
= 1.21
The p value will be:
= 2 × P(z > 1.21)
This is because it's two tailed. The value will be looked in the probability table.
= 2(0.1131)
= 0.23
The value is 0.23.
