Regular consumption of presweetened cereals con- tributes to tooth decay, heart disease, and other degen- erative diseases, according to studies conducted by Dr. W. H. Bowen of the National Institute of Health and Dr. J. Yudben, Professor of Nutrition and Dietetics at the University of London. In a random sample con- sisting of 20 similar single servings of Alpha-Bits, the average sugar content was 11.3 grams with a standard deviation of 2.45 grams. Assuming that the sugar con- tents are normally distributed, construct a 95% con- fidence interval for the mean sugar content for single servings of Alpha-Bits. Above and the number 9.9 attachment is the referred question of the 9.17 problem

9.18 Referring to Exercise 9.13, construct a 95% tol-
erance interval containing 90% of the measurements.

9.9 Regular consumption of presweetened cereals con-
tributes to tooth decay, heart disease, and other degen-
erative diseases, according to studies conducted by Dr.
W. H. Bowen of the National Institute of Health and
Dr. J. Yudben, Professor of Nutrition and Dietetics at
the University of London. In a random sample con-
sisting of 20 similar single servings of Alpha-Bits, the
average sugar content was 11.3 grams with a standard
deviation of 2.45 grams. Assuming that the sugar con-
tents are normally distributed, construct a 95% con-
fidence interval for the mean sugar content for single
servings of Alpha-Bits.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
