Given that integer array x has elements 5, 10, 15, 20, what is the output?

The p-value of the test is the calculated probability. Hence, the probability must be 18/380. In simplified terms, this is equal to 0.0474 or 4.74%. This is the p-value of the test. The null hypothesis is p < 6%. According to the test, the p-value is 4.74%. Therefore, the null hypothesis is accepted. 

The answer is not among the choices. The answer must be 0.0474 or 4.74%.
