In one experiment 9 batteries of each brand (Energizer and Ultracell) were brought up to 1 volt. The number of pulses was recorded. The higher the number of pulses the longer lasting is the battery. The mean number of pulses for Energizer was 258.78. The mean for Ultracell was 411.33. Find the difference in means Energizer minus Ultracell.
Solution :
Given that ,
The mean number of pulses for Energizer was 258.78.
The difference in means Energizer minus Ultracell is = 258.78 - 411.33 = -152.55

Question 5 4 pts For each of the following studies, select the appropriate method of analyzing the data. I am interested in comparing three different battery brands to determine if a different exists in how long, on average, the batteries last. Batteries from Duracell, Energizer, and a generic battery brand were all randomly sampled and tested in a variety of electronic devices. The goal is to compare the average battery life of the three brands and, ideally, rank the brands...

A cell phone battery manufacturer claims that one of their batteries for a particular cell phone will outperform a competitor's equivalent brand. To establish this claim, a researcher selected samples of the two brands of batteries and perform accelerated tests on them in the lab under identical conditions. A random sample of 55 of the manufacturer's battery was selected and placed on test. A corresponding random sample of 55 of the competitor's battery was also put...
A taxi company is trying to decide whether to purchase brand A or brand B tires for its fleet of taxis. To estimate the difference in the two brands, an experiment is conducted using 8 of each brand, assigned at random to the left and right rear wheels of 8 taxis. The tires are run until they wear out and the distances, in kilometers, are recorded in the accompanying data set. Find a 90% confidence interval for y- H2. Assume...
A consumer products testing group is evaluating two competing brands of tires, Brand 1 and Brand 2. Tread wear can vary considerably depending on the type of car, and the group is trying to eliminate this effect by installing the two brands on the same random sample of 8 cars. In particular, each car has one tire of each brand on its front wheels, with half of the cars chosen at random to have Brand 1 on the left front...

An experiment randomly assigned 263 adults to watch one of 3 TV programs. One group watched a violent program, the second watched a program with sexual content and the last group watched a neutral program. After viewing the program each participant was scored on their recall of the brand names in the commerical messages. The researchers compared the mean recall scores of the three viewing groups with an analysis of variance for a completely randomized design. Complete parts a through...
Consider an experiment in which 45 zirconium disks were divided into five groups of 9 each. Then a different contamination/cleaning protocol was used for each group. Use Tukey's procedure on the data below to identify differences in true average bond strengths (MPa) among the five protocols. (Use α = 0.05.) Treatment: 1 2 3 4 5 Sample mean 10.5 14.8 15.7 16.0 21.6 Grand mean = 15.7 Sample sd 4.2 6.8 6.2 6.9 6 MSE = 37.186 Find the value...
In an experiment to investigate the performance of four different brands of spark plugs intended for use on a 125-cc motorcycle, five plugs of each brand were tested, and the number of miles (at a constant speed) until failure was observed. A partially completed ANOVA table is given. Fill in the missing entries, and test the relevant hypotheses using a .05 level of significance. (Give the answer to two decimal places.)

To illustrate the effects of driving under the influence (DUI) of alcohol, a police officer brought a DUI simulator to a local high school. Student reaction time in an emergency was measured with unimpaired vision and also while wearing a pair of special goggles to simulate the effects of alcohol on vision. For a random sample of nine teenagers, the time (in seconds) required to bring the vehicle to a stop from a speed of 60 miles per hour was...
