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

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
