The mean life of a battery used in a digital clock is 305 days. The lives of the batteries follow the normal distribution. The battery was recently modified with the objective of making it last longer. A sample of 20 of the modified batteries had a mean life of 311 days with a standard deviation of 12 days. Did the modification increase the mean life of the battery?
a. State the null hypothesis and the alternate hypothesis.
b. Show the decision rule graphically. Use the .05 significance level.
c. Compute the value of t. What is your decision regarding the null hypothesis? Briefly summarize your results.
Conduct post hoc comparisons with the LSD method. Which groups differ significantly at α = 0.05?
In the real world, a given null hypothesis is false; but the collected data lead to the null hypothesis being accepted. That is, the data lead to a failure to reject the null hypothesis.
What is the probability of the person is 20 to 24 years old.What is the probability of the person is 20 to 34 years old.
Taking α to be 0.05, what is/are the critical values associated with testing your hypothesis?
Make a decision regarding the null hypothesis based on the sample information. Interpret the results of the test and state your conclusion.
The mean of a standard normal probability distribution.
The scores of college-bound senior men on the math part of the SAT followed a normal distribution with mean 527 and standard deviation 116.
Binomial Distribution: Control Charts this problem will be referred to in the study of control charts. In the binomial probability distribution, let the number of trials be n = 3, and let the probability of success be p = 0.0228.
When the level of confidence and sample standard deviation remain the same, a confidence interval for a population mean based on a sample of n = 100
An experiment consists of flipping the fair coin three times and noting the number of heads and tails. A random variable x is defined to be two times the number of heads plus the number of tails.
Give null and alternative hypotheses for this test in symbolic form.
