7. Suppose it is claimed that amongst the population of human adults, the number of hoursspent sleeping per day is normally distributed with a mean of μ = 7 and variance of o² = 1.1Further suppose that we wish to study the mean of the population by taking a randomsample of n = 62 adults.9. Again following on from the previous question, what is the probability that when we take arandom sample of n = 62 adults, the sample mean would be either greater than 7.133 or lessthan 6.867?

given data μ = 7σ2 = 1.1n = 62P(x¯>7.133 or x¯<6.867) = ?

Answered: 7. Suppose it is claimed that amongst…

Suppose that we have disjoint normal populations A and B with equal population variances. Suppose we plan a sample of size 4 from from population A and a sample of size 9 from population B which we will pool to form the pooled variance. If you know the population variances are both in fact equal to 6, what is the probability that the pooled variance of the two samples will turn out to be less than 8 given your information?

We will conduct a hypothesis test at the 10% level of significance to determine whether there is evidence that the true mean fuel efficiency of all cars of this make and model differs from 32 mpg.
