6.3 Confidence Interval for Proportions: Check for Understanding Sleep Awareness Week begins in the spring with the release of the National Sleep Foundation's annual poll of U.S. sleep habits and ends with the beginning of daylight savings time, when most people lose an hour of sleep. In the foundation's random sample of 1029 U.S. adults, 48% reported that they "often or always" got enough sleep during the last 7 nights. 1. Identify the parameter of interest. 2. Check if the conditions for constructing a confidence interval for p are met. 3. Find the critical value for a 98% confidence interval. Then calculate the interval. 4. Interpret the interval in context.

Tips It’s commonly believed that people use tips toreward good service. A researcher for the hospitalityindustry examined tips and ratings of service qualityfrom 2645 dining parties at 21 different restaurants. The correlation between ratings of service and tip percent-ages was 0.11. (M. Lynn and M. McCall, “Gratitude and Gratuity.” Journal of Socio-Economics 29: 203–214)a) Describe the relationship between Quality of Serviceand Tip Size.b) Find and interpret the value of R2 in this context.
5.28 Risks and insurance. The idea of insurance is that we all face risks that are unlikely but carry high cost. Think of a fire destroying your home. So we form a group to share the risk: we all pay a small amount, and the insurance policy pays a large amount to those few of us whose homes burn down. An insurance company looks at the records for millions of homeowners and sees that the mean loss from fire in a year is μ = $250 per house and that the standard deviation of the loss is σ = $1000. (The distribution of losses is extremely right-skewed: most people have $0 loss, but a few have large losses.) The company plans to sell fire insurance for $250 plus enough to cover its costs and profit. If the company sells 25,000 policies, what is the approximate probability that the average loss in a year will be greater than $270?

Custom-Home Resales. Regarding predicting the selling price of a home in the Equestrian Estates using the predictor variables square footage, number of bedrooms, number of bathrooms, and number of days on the market. The confidence and prediction intervals are for homes that have 3200 sq ft, 4 bedrooms, 3 bathrooms, and that remain on the market for 60 days. a. Obtain a point estimate for the mean selling price of all homes in the Equestrian Estates that have 3200 sq ft, 4 bedrooms, 3 bathrooms, and that remain on the market for 60 days. b. Obtain a 95% confidence interval for the mean selling price of all homes in the Equestrian Estates that have 3200 sq ft, 4 bedrooms, 3 bathrooms, and that remain on the market for 60 days. c.

Q.No.1. Read the following passage and observe the word length of each word. Make a frequency distribution of word length. "Statistics play an intrinsic role in computer science and vice versa. Statistics is used for data mining, speech recognition, vision and image analysis, data compression, artificial intelligence, and network and traffic modeling. A statistical background is essential for understanding algorithms and statistical properties that form the backbone of computer science. Typically, statistical approach to models tends to involve stochastic (random) models with prior knowledge of the data. The computer science approach, on the other hand, leans more to algorithmic models without prior knowledge of the data. Ultimately, these come together in attempts to solve problems."

K Do freshmen spend significantly more time on social media than other class ranks? A recent study investigated the amount of time per day freshmen, sophomores, juniors, and seniors spent on social media while doing schoolwork. The students surveyed were U.S. residents from a 4-year, public, primarily residential institution. The accompanying computer output shows the mean time each cohort spent on social media and an ANOVA table. Construct a 95% confidence interval to compare the population mean time spent per day on social media between freshmen and seniors. Click the icon to view the summary statistics and ANOVA table.
