See picture and answer C and D.(c)Which class had test scores with a larger interquartile range (IQR)? Choose one (Class A/ Class B/ Both had the same IQR)(d)Which class had the highest test score? Choose one (Class A/ Class B/ Both had the highest) Two English classes with the same number of students took a final exam.The box-and-whisker plots below (sometimes called boxplots) summarize the test scores for each class.Use the box-and-whisker plots to answer the questions.Class AClass B556065707580859095Test score

Given: The boxplots are shown belowBoxplot is one of the graphical methods that is drawn for the quantitative variable to explain the spread of the data set. Using boxplot 5 number summaries are plotted, Following are 5 number summary: These are defined as: 1. Minimum value = Lowest value of the provided data set and is represented by first dot. 2. First quartile = Observations that falls below 25% of the data set and is represented by the start of the box 3. Median = Middle value of the data set and is represented by middle line of the box 4. Third quartile = Observations that falls above 75% of the data set and is represented by end of the box 5. Minimum value = Highest value of the provided data set and is represented by last dot .From the above plots, the 5 number summaries are shown below City A Minimum = 58 First quartile (Q1) = 60 Median = 66 Third quartile (Q3) = 68 Maximum = 92 City B Minimum = 59 First quartile (Q1) = 70 Median = 74 Third quartile (Q3) = 78 Maximum = 80c) larger interquartile range (IQR) For city A IQR = Q3 - Q1 = 68 - 60 = 8 For city B IQR = Q3 - Q1 = 78 - 70 = 8 Both had same IQR at 8. The correct option is Both had same IQR.Highest test score From the given information, city A has maximum score of 92 and city B has 80 So, City A has highest test score. The correct option is City A.

Twenty years ago, 51% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 309 of 900 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a= 0.01 level of significance. Because npo (1- po) = 243.5 > 10, the sample size is less than 5% of the population size, and the sample is given to be random, the requirements for testing the hypothesis are satisfied. (Round to one decimal place as needed.) What are the null and alternative hypotheses? Ho: 51 versus H1: 51 (Type integers or decimals. Do not round.) Find the test statistic. Zo = 1.96 (Round to two decimal places as needed.) Find the P-value. P-value = .025 (Round to three decimal places as needed.) Determine the conclusion for this hypothesis test. Choose the…
