- Please give an answer with a calculation and give an explanation of the correct and incorrect option.arrow_forwardIf the 2412 leaves are not a random sample, but the researchers treated the 2412 leaves as a random sample, this most likely made the data more: accurate, but not precise precise, but not accurate neither both accurate and precisearrow_forwardThe Wisconsin Fish and Game Department stocked a lake with 30% catfish, 15 % bass, 40% bluegill, and 15% Northern Pike. Five years later they took a random sample of 500 fish from the lake and found 120 catfish, 85 bass, 220 bluegill, and 75 Northern Pike. At the 5% level of significance, can we show that the distribution of fish changed over the 5-year interval? State and test appropriate hypotheses. State conclusions.arrow_forward
- In each situation, find the value of the t-statistic for the sample mean x and give the value of degrees of freedom (df). (a) x = 6, µ = 12, o = 24, n = 25 t = df = (b) x = 18, u = 12, o = 24, n = 25 t = df =arrow_forwardPart I: Sections 1.1 - 1.5 4. A flower garden has 40 flowers: 10 yellow, 5 white, 8 red, and 17 pink. Assume that 3 flowers are randomly selected. If the sampling is done with replacement, what is the (a) probability that the first two flowers are pink and the last flower is yellow? (b) probability that at least one of the flowers is red? If the sampling is done without replacement, what is thearrow_forwardUSE EXCEL to solve this problem. Thanks.arrow_forward

- Last school year, the student body of a local university consisted of 20% freshmen, 21% sophomores, 29% juniors, and 30% seniors. A random sample of 300 students taken from this year's student body showed the following number of students in each class. Freshmen 84 Sophomores 65 Juniors 86 Seniors 65 We are interested in determining whether there has been a significant change in the distribution of class between the last school year and this school year.If the distribution is the same as the previous year, the expected number of freshmen is _____. a. 84 b. 87 c. 60 d. 20arrow_forwardHans plays a game when he exercises. He chooses a marble from a bag of three marbles: one is blue, one is red, and one is green. Based on the marble he chooses, he completes a certain number of push-ups, as shown below. Marble Number of push-ups blue red green 10 Consider choosing a marble like sampling from a population. (The population mean of the number of push-ups is u=9.00 and the population standard deyiation is o =0.82.) (a) Suppose a sample of size 2 is randomly selected from the population, with replacement, as follows. One marble is randomly chosen, the number of push- ups is completed, and the marble is put back into the bag. Then for a second time a marble is randomly chosen and the number of push-ups is completed. There are 9 possible samples. The numbers of push-ups for several of the possible samples have been listed in the table below. Enter the numbers of push-ups for the remaining possible samples. When you are done, select "Compute".
