F(144) Generation Y has been defined as those individuals who were born between 1981 and 1991. A 2010 survey by a credit counseling foundation found that 60% of the young adults in Generation Y pay their monthly bills on time. Suppose we take a random sample of 190 people from Generation Y. Question content area bottom Part 1 The distribution of p is a aproximately normal. Calculate the standard deviaiton of p. σp=enter your response here(Round to four decimal places as needed.) What is the probability that between 106 and 120 of them will pay their monthly bills on time?

Suppose that the lengths of pregnancies are normally distributed with a mean of 271 days and a standard deviation of 10 days. find the percentage of pregnancies that are longer than 254 days. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%).
1.42 Solver and least squares fits 1.43 Error and statistics The objectives of this section are to: 1. Create error bars within a chart in a spreadsheet. 2. Apply statistics-related functions for a data series. 3. Calculate and distinguish between standard deviation and quartiles for a data series. 4. Complete a linear regression within a spreadsheet using functions or built-in regression tools. Error and error bars An error is commonly known as a mistake, but in a spreadsheet, an error usually quantifies a statistical difference. Ex: A residual is the difference between the data and model, which is detailed in another section, and is one example of a quantifiable error. When plotting data and models in charts, error bars provide one method to visualize quantified error. The animation below shows several types of error bars.

Chapter 5, Section 2, Exercise 043 Hearing Loss in TeenagersA recent study1 found that, of the 1771 participants aged 12 to 19 in the National Health and Nutrition Examination Survey, 19.5% had some hearing loss (defined as a loss of 15 decibels in at least one ear). This is a dramatic increase from a decade ago. The sample size is large enough to use the normal distribution, and a bootstrap distribution shows that the standard error for the proportion is SE=0.009.Find a 95% confidence interval for the proportion of teenagers with some hearing loss.Round your answers to two decimal places.The 95% confidence interval is to .

You decide that you want to make sure your estimate from part a is correct. You go out and gather 10 simple random samples of 25 people in your school and calculate the proportion of students within each sample whose Amazon packages arrive within two business days of ordering. The proportion of customers that receive their packages within two days of ordering are given below. 0.70, 0.75, 0.6, 0.95, 0.90, 0.73, 0.87, 0.86, 0.92, 0.97 Explain why all of the sample proportions are not the same.
