Homework Answers
a)
H0: mu = 8.5
b)
Type I error occurs when one incorrectly rejects the null
hypothesis
Here type I error will occurs if a conclusion is made to that mean height is greater than 8.5 inches however actually it is 8.5 inches.
c)
Type II error occurs when one incorrectly fails to reject the null
hypothesis
Here type II error will occur if a conclusion is made that the mean height is 8.5 inches however actually it is greater than 8.5 inches.
d)
When type I error occurs, farmers who will use the fertilizer will
suffer most.

Suppose the mean height of women age 20 years or older in a certain country is 62.6 inches. One hundred randomly selected women in a certain city had a mean height of 61.5 inches. At the 11% significance level, do the data provide sufficient evidence to conclude that the mean height of women in the city differs from the national mean? Assume that the population standard deviation of the heights of women in the city is 3.63.6 inches. Set up...

A new treatment has been developed for a certain type of cement, resulting in a mean pressure resistance of 5000kg/cm² and a standard deviation of 130kg/cm². To verify the null hypothesis of p = 5000 against the alternative of u <5000, a random sample of 50 pieces of cement are examined.

11) In the past, the mean battery life for a certain type of flashlight battery has been 8.8 hours. The manufacturer has introduced a change in the production method and wants to perform a hypothesis test to determine whether the mean battery life has increased as a result. The hypotheses are: Ho: = 8.8 hours H4> 8.8 hours a) Explain the result of a Type I error. b) Explain the result of a Type II error.

A coin-operated coffee machine made by BIG Corporation was designed to discharge a mean of 7.1 ounces of coffee per cup. If it dispenses more than that on average, the corporation may lose money, and if it dispenses less, the customers may complain. Believing that the mean amount of coffee dispensed by the machine, , is different from 7.1 ounces, BIG plans to do a statistical test of the claim that the machine is working as designed. Technicians gather a...

A scientist has read that the mean birth weight, H, of bables bom at full term is 7.3 pounds. The scientist, belleving that he is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies bom at full term and finds the mean of the sample to be 7.6 pounds and the standard deviation to be 1.5 pounds. Based on this information, answer the questions below. What are the nut...
