Management will become concerned if more than 10% of the widgets from a particular machine are out of tolerance. Calculate the 5th percentile and the 95th percentile to find the measurements you would use to evaluate management's concern.
Give an 80% confidence interval for the total number of signatures. How (if at all) does the non-normality of the Number of signatures (with a greatest frequency at the upper end - 42) affect your answer?
In this problem, we explore the effect on the standard deviation of adding the same constant to each data value in a data set. Consider the following data set.
The random variable X has a Poisson distribution with mean 40. Give an approximate value of the probability P( 37 less than or equal to X less than 41 ) using the central limit theorem with a continuity correction. Show work.
A) What is the lottery's expected profit per ticket? B) What is the lottery's standard deviation of profit per ticket?
How should you calculate confidence interval using quantiles from a t-distribution and with how much degree of freedom? Is it approprait to use in calculating the confidence of interval quantiles from a normal distribution?Explain and show work.

Developmentally Appropriate Language: Clinicians simplify their language, avoiding jargon, and using short sentences to ensure comprehension.
Observational Techniques: Since infants may not be able to verbally articulate their feelings, clinicians often rely on observation of behaviors,
