An article reported that for a sample of 52 kitchens with gas cooking appliances monitored during a one-week period, the sample mean CO2 level (ppm) was 654.16, and the sample standard deviation was 166.25.

(a) Calculate and interpret a 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected. (Round your answers to two decimal places.) .......................................... , .............................................. ppm

Expert Solution

TOPIC:Confidence interval for the population proportion.

INTERPRETATION:

We are 95% confident that the true population average CO₂ level in the population of all homes, will fall within the interval

(607.88 , 700.44) ppm. (ANSWER)

A cooking article reported that cooking a quality meal takes time; in fact, the article states that it takes longer than 45.0 minutes. Suppose a study is conducted to test the validity of this statement at a 95.00% confidence interval/level. A sample of 18 people is selected, and the length of time to put a meal on the table is listed: 45.20 40.70 41.10 49.10 30.90 45.20 55.30 52.10 45.40 55.10 38.80 43.10 39.20 58.60 49.80 43.20 47.90 46.60 What...

Cholesterol: An article in the Archives of Internal Medicine reported that in a sample of 250 men, 55 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 210 women, 50 had elevated cholesterol levels. Can you conclude that the proportion of men with elevated cholesterol levels is less than the proportion of women with elevated cholesterol levels? Let p1 denote the proportion of men with elevated cholesterol levels and p2 denote the proportion of...

An article investigated the consumption of caffeine among women. A sample of 52 women were asked to monitor their caffeine intake over the course of one day. The mean amount of caffeine consumed in the sample of women was 226.553 mg with a standard deviation of 229.462 mg. In the article, researchers would like to include a 99% confidence interval. The values below are t critical point corresponding to 90%, 95%, 98%, and 99% confidence. Which critical point corresponds...
