We wish to test whether or not there is a difference between two of our production lines in terms of the defect rate. We examine 400 products on Line A and find that 40% are defective, whereas we examine 100 products on Line B and find that 20% are defective. What is the appropriate test statistic here?

Suppose that we wish to test whether the population mean of weights of male students at a certain college to be larger than 68 kilograms. Consider α = 0.05 level of signiﬁcance and assume normal population. We have a random sample with size 10, x = 70 and s^2 = 10. 1. Complete the test by ﬁnding out its critical region and draw your conclusion. 2. Complete the test by ﬁnding out its p-value and draw your conclusion. Is your...

In a t-test, when we see a difference in the means but our test leads us to accept the null hypothesis, we: Select one: 1. claim that a significant difference exists between groups. 2. have obtained a t-value greater than our critical t-value. 3. have committed a Type 1 error. 4. conclude that the difference is a result of the sampling error.

We wish to study the difference in attitudes between urban residents versus suburban residents in a metropolitan area as these attitudes relate to the proposed construction of a nuclear plant in the area. We obtain a random sample of 80 urban residents and find that 60 of these residents favor the construction of the plant. Independently, we obtain a random sample of 100 suburban residents, finding that 65 of these residents favor construction of the plant. Select the correct expression...
