A farmer wants to see if there is a difference in average yield between two varieties of corn (varietyA and variety B). In order to compare the two varieties, he prepares a two-acre plot on each of hisseven different fields. On each field he plants variety A on a one acre plot and variety B on the oneacre plot right next to it. Which acre plot gets which variety is determined at random. At harvesttime, he measures the yield (in bushels) on each of the acre plots.FieldVariety A1234567148.2144.6149.7140.5154.6147.1151.4Variety B141.5141.0144.0141.2153.0141.7146.8Assuming that the conditions for inference are met, what statistical test should be used to determineif there is a significant difference in average yield between the two com varieties?(A) A chi-square goodness-of-fit test(B) A chi-square test of independence(C) A matched-pairs 1-test for means(D) A two-sample t-test for means(E) A linear regression /-test

The quantity of dissolved oxygen is a measure of water pollution in lakes, rivers, and streams. Water samples were taken at four different locations in a river in an effort to determine if water pollution varied from location to location. Location I was 500 meters above an industrial plant water discharge point and near the shore. Location II was 200 meters above the discharge point and in midstream. Location III was 50 meters downstream from the discharge point and near the shore. Location IV was 200 meters downstream from the discharge point and in midstream. The following table shows the results. Lower dissolved oxygen readings mean more pollution. Because of the difficulty in getting midstream samples, ecology students collecting the data had fewer of these samples. Use a 5% level of significance. Do we reject or not reject the claim that the quantity of dissolved oxygen does not vary from one location to another? Location I Location II Location III Location IV 7.6 6.3 4.6…

Eric gave a large bowl of puppy chow to each of 80 puppies and recorded how many ounces of food they ate during a given time period. He kept track of each puppy's breed and the brand of chow they ate. The means for each condition are shown in the table. To answer the questions below, examine the means. Assume differences between means of at least 2 units are significant. Purina Blue Buffalo Border collie 5.35 2.15 Bulldog 3.15 7.70 A. From the data in the table, does it look like there is a significant main effect of the brand of food? а. yes b. no B. If you said there is an effect in the previous question, please describe it. C.

A drug company claims that an allergy medication causes headaches in 5% of those who take it.A medical researcher believes that more than 5% of those who take the drug actually get headaches. Identify the population(s): All individuals who take the medication. The proportion of those who take the drug who get a headache. What is the variable being examined for individuals in the population(s)? Whether or not an individual who does not take the drug gets a headache. Whether or not an individual takes the correct dosage of the drug. Whether or not an individual who takes the drug gets a headache. Is it categorical or quantitative? [Proportions are Categorical. Mean values are Quantitative.] Categorical Quantitative Identify the parameter(s): The proportion of those who take the drug who get a headache. The mean amount of medication taken. The number individuals who take the medication. What kind of hypotheisis test is this? 1 population mean 2 population means 2…

To detect the presence of harmful insects in farm ﬁelds, we can put up boards covered with a sticky material and examine the insects trapped on the boards. Which colors attract insects best? Experimenters placed boards of several colors at random locations in a ﬁeld of oats (four colors and six boards of each color). Make a plot of the number of beetles trapped on each board against the board's color, arranging the colors to show blue ﬁrst, then white, then green, and last yellow (space the four colors equally on the horizontal axis).
In 2016 the Better Business Bureau settled 84% of complaints they received in the United States. Suppose you have been hired by the Better Business Bureau to investigate the complaints they received this year involving new car dealers. You plan to select a sample of new car dealer complaints to estimate the proportion of complaints the Better Business Bureau is able to settle. Assume the population proportion of complaints settled for new car dealers is 0.84, the same as the overall proportion of complaints settled in 2016. Use the z-table. a. Suppose you select a sample of 200 complaints involving new car dealers. Show the sampling distribution of p. E(p) (to 2 decimals) (to 4 decimals) b. Based upon a sample of 200 complaints, what is the probability that the sample proportion will be within 0.04 of the population proportion (to 4 decimals)? probability : = c. Suppose you select a sample of 460 complaints involving new car dealers. Show the sampling distribution of p. E(F) (to 2…
