An experiment was conducted to study the life (in hours) of two different brands of batteries in threedifferent devices (radio, camera, and portable DVD player). A completely randomized two-factorexperiment was conducted, and the following data resulted.Brand Deviceof Battery Radio Camera DVD PlayerA 8.6 7.9 5.48.2 8.4 5.7B 9.4 8.5 5.88.8 8.9 5.9(a) Analyze the data and draw conclusions, using α = 0.05. (b) Investigate model adequacy by plotting the residuals. (c) Which brand of batteries would you recommend?
In a completely randomized experimental design involving four treatments, 20 observations were recorded for each of the four treatments. The following information is provided: SSTR = 154 and SST = 342. What does the sum of squares within treatments (SSE) equal?
In a completely randomized design experiment, 10 experimental units were randomly chosen for each of three treatment groups and a quantity was measured for each unit within each group. In the first steps of testing whether the means of the three groups are the same, the sum of squares for treatments was calculated to be 3,110 and the sum of squares for error was calculated to be 27,000. Complete the ANOVA table. Source df SS MS F Treatments Error Total
In the search for a cure for the Coronavirus, it is important to determine what proportion of the population has antibodies, which would likely make them immune or less susceptible to the effects of the disease. According to an article in Politico published on April 26, 2022, 60% of Americans currently have detectible antibodies for Covid-19. A researcher thinks that more than 60% of Americans currently have antibodies for Covid-19. Suppose that the researcher takes a simple randomsample of 1200 Americans, tests their blood, and find that 750 of them have antibodies. Use a 0.05 significance level to test the researcher’s claim.
A telemarketing firm has studied the effects of two factors on the response to its television advertisements. The first factor is the time of day at which the ad is run, while the second is the position of the ad within the hour. The data in the following table, which were obtained by using a completely randomized experimental design, give the number of calls placed to an 800 number following a sample broadcast of the advertisement. If we use Excel to analyze these data, we obtain the output in the table below.

Bicycle frames can be made from carbon, steel, or othermaterials. Carbon frames are much more expensive thansteel, but they are also much lighter. Could this lighter frame have a significant impact on speed? In 2010 a doc-tor in England, who commutes daily to work 27 miles roundtrip on a bicycle, ran his own randomized experi-ment to investigate. Each day for several months Dr. Groves flipped a coin todetermine whether he would ride his steel frame bicycle orhis carbon frame bicycle to work and back. He rode a totalof 30 journeys on the steel frame bike and 26 journeys onhis carbon frame bicycle, recording his total commutingtime for each day. The summary statistics are shown below:a) Why would you prefer to see the actual data beforeproceeding with inference?b) Construct and interpret a 95% confidence interval forthe difference in average commuting times.c) Explain in this context what “95% confidence”means.d) Based on your confidence interval, do the doctor’sdata provide evidence…
Turtles are one of the longest existing creatures in the world. Due to several environmental factors, many species of turtles are already endangered. A wildlife biologist would like to study the effect of two randomly selected substrates during incubation (A1 = sand, A2 = vermiculite) and temperature (B1 = 25°C, B2 = 30°C) on the number of days before a turtle egg is hatched. The experiment was laid out in CRD with five replications.
Which of these statements is NOT true regarding a randomized block design experiment? a.) The elements are randomly allocated to treatment and control groups. b.) The sample is divided into participants or subjects and then grouped by a variable of interest. c.) This design has the advantage of controlling for variables that might confound the response. d.) Elements are randomly selected from equal-sized blocks of the total population.
