Answer:
The test statistic is
Step-by-step explanation:
From the question we are told that
The population mean is
The The level of significance is
The sample size is n = 18
The null hypothesis is
The alternative hypothesis is
The sample mean is
The standard deviation is
Generally the test statistics is mathematically represented as
substituting values
Solution
The table below is the required sample space of the to fair die
From the above table
The sample space contain 36 outcomes
Event A: The sum is greater than 9
we will look at the table and count all the elements that are greater than 9
There are 6 elements (they are 10, 10, 10, 11, 11, 12 from the table)
The probability for event A will be
P(A) = 1/6
Event B: The sum is an even number.
We will look at the table and count the number of elements that are even
There are 18 elements (notice that there are 3 even number on each of the 6 rows of the table)
The probability for event B will be
p(B) = 1/2
