Histogram data – I know the answer, but how I can get it?
The amount of television watching by young people today is a major concern for parents watching television cons (PAWT). 300 parents of school-age children were invited to estimate the number of hours week your child watch television. The mean and standard deviation of their responses were 14 and 3, respectively. A histogram of the data shows that the distribution time was symmetric and mound-shaped distribution. Provide a range where you think about 95% of primetime television decreased distribution. The answer is: between 8 and 20 hours per week, but I can get one?
I think the answer specified is not true that the approximate 95% confidence interval is the mean = + / – Critical / standard deviation of value z * 14 + / – 1.96 3 * Lower limit of agreement range from 14 to 5.88 = 8.12 = upper limit of the range = 14 + 5.88 = 19.88 If the response is displayed for 8 and 20 confidence limit must be 95.44% z value is in the area under the standard normal curve tables critical value or z value of 1.96 is 95% and 95.44% is 2
