A researcher knows that the weights of 6-year olds are normally distributed with a mean of 22.7 kg ando = 2.6 kg. She suspects that children in poverty-stricken regions are undernourished and thereforeunderweight. With a sample of N = 25 children, the researcher obtains a sample mean of X = 20.9kg.(a) Compute a 95% confidence interval for u, the population mean weight for children in poverty-stricken regions.(b) Perform a hypothesis test to decide whether children in poverty-stricken regions are significantlyunderweight.

The electric cooperative needs to know the mean household usage of electricity by its non-commercial customers in kWh per day. They would like the estimate to have a maximum error of 0.14 kWh. A previous study found that for an average family the variance is 4.84 kWh and the mean is 19.1 kWh per day. If they are using a 80% level of confidence, how large of a sample is required to estimate the mean usage of electricity?

A confidence interval is desired for the true mean stray-load loss (Watts) for a certain type of induction motor. Assume that the stray-load loss is normally distributed with =3.3Watts. Situation 3: You take 100 measurements of stray-load loss from induction motors and determine that the mean of your sample is 53.6 Watts. When you calculate the 95% confidence interval for this situation, you get: (52.95 Watts, 54.25 Watts) is a 95% confidence interval for M. Compare this confidence interval to the interval you calculated in Situation 1. They are both 95% confidence intervals, but they have different sample sizes. What effect did sample size have on the interval estimate endpoints? Question 1: 25 sample size, Confidence Interval: (52.3064,54.8936)
