(Round your answers to one decimal place.) , ksi in Is this interval valid whatever the nature of the distribution? Explain. The interval is always valid. The distribution needs to be skewed to the right. The distribution needs to be approximately uniform. The distribution needs to be approximately normal.

An NHANES report gives data for 652 women aged 20 – 29 20–29 years. The BMI of these 652 652 women was ¯ x = 26.5 x¯= 26.5 . On the basis of this sample, we want to estimate the BMI μ μ in the population of all 20.6 20.6 million women in this age group. We treated these data as an SRS from a Normally distributed population with standard deviation σ = 7.2 σ=7.2 . Give three confidence intervals for the mean BMI μ in this population, using 90%, 95%, and 99% confidence. Enter the lower and upper bound for the 90% confidence interval.

Your local pizza chain claims that the delivery time of their pizzas is normally distributed with a mean of 30 minutes and standard deviation of 10 minutes. Twenty of your friends in different locations order pizzas and the average delivery time is 42 minutes with standard deviation of 10 minutes. Compute a one-sample t statistic. Do you have a reason to disbelieve the chain’s claim?
