2. A fair coin is tossed, and a fair six-sided die is rolled. Suppose the outcomes for the coin and die are independent. The probability of getting a head and rolling a six isA. 1/12.B. 2/3.C. 1/3.
The standard deviations s1 and s2 can be used when Ó1 and Ó2 are unknown and you believe that the underlying distribution is normal. Then, you would use s1 and s2 with the t-test for hypothesis testing.
You conduct a hypothesis test and you observe values for the sample mean and sample standard deviation when n=25 that do not lead to the rejection of the null hypothesis (the p value is .0667).
