Suppose the mean of a normally distributed population is 300, and 200 simple random samples are drawn from the population. At a 68% confidence level, (one standard deviation from the mean), about how many of the samples’ confidence intervals would you expect to contain the population mean? 64 96 136 204

136

Step-by-step explanation:

This question is poorly phrased.  However, the answer must be 0.68*200=136.

The reason is that, by definition, an X% confidence range is computed in such a way that the expected percentage of X% confidence ranges constructed over many samples that will contain the true mean is X%.

136

Step-by-step explanation:

None

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

answer: 2 and 1
