If the new supplier does provide spools of .20-mm solid OFE copper wire that average 50 inches between flaws, how is the length of wire between two consecutive flaws distributed? 2. Using the probability distribution you identified in (1), what is the probability that Gebhardt's criteria will be met (i.e., a 1 in 20 chance that a randomly selected 3-foot segment of wire provided by the new supplier will be flawless)? 3 3. In inches, what is the minimum mean length between consecutive flaws that would result in satisfaction of Gebhardt's criteria? 4. In inches, what is the minimum mean length between consecutive flaws that would result in a 1 in 100 chance that a randomly selected 3-foot segment of wire provided by the new supplier will be flawless? E 20…

Please solve part d, e, f, g. In a certain jurisdiction, all students in Grade Three are required to take a standardized test to evaluate their math comprehension skills.The file contains these data resulting from a random sample of n=30 schools within this jurisdiction. From these data you wish to estimate the model Yi=β0+β1Xi+ei where Xi is the percentage of Grade Three students in School i who live below the poverty line and Yi is the average mathematics comprehension score for all Grade Three students in the same school, School i. The observed data for the X variable is labled perbelowpoverty and the observed data for the Y variable is labeled mathscore in the file.Import (either hand type or load the file) data into R Studio, then answer the following questions based on the data.(a) Create a scatterplot of the data. What can you say about the nature of the relationship between the percentage of Grade Three students living below the poverty line in a certain school and the school's…

Please answer this question show below correctly, read the problem carefully and identify the experimental units, response units, response variables, factors, levels of each factor and treatments in this example.

Detailed solution thank you.

The picture for the dataset for AIDS cases below include the numbers of cases of AIDS in Australia by date of diagnosis for successive 3-month periods from 1984 to 1988. (Data from National Centre for HIV Epidemiology and Clinical Research, 1994.) Answer parts 1, 2, and 3 below. Please explain with detail. 1.) Identify the type and scale of each variable (measurement) 2.) Identify the primary outcome of interest (Y) 3.) Identify the factors that affect the value of Y (X)

A professor at the University of Iowa was interested in evaluating whether domestic dispute calls were more dangerous to officers than other types of calls. Collecting information on call for service and whether the call resulted in officer injury. The data is displayed in the contingency table below.       Type of Call     Domestic Dispute Not a Domestic Dispute Officer Injury No 128 675   Yes 245 786     Using the information to complete Table 1 and answer the questions below.   Table 1. Chi-square (4 points, 1 per column) Category Observed Expected O – E (O – E)2 (O – E)2/E No, Domestic 128         No, Not Domestic 675         Yes, Domestic 245         Yes, Not Domestic 786                   What is the scale of measurement of the dependent variable?     What is the value for the chi-square?     Using an alpha level of 0.05, what is the critical…

PLEASE ANSWER ALL PARTS OF THE QUESTION AND USE THE IMAGE FOR A GUIDE A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas numbered 17—32.   The biologist chooses 16 plots at random and applies organic fertilizer. The other plots receive non-organic fertilizer. At the end of the study period, the percentage increase in the number of this plant is measured in each plot and compared for each type of fertilizer. Is this an experiment? Briefly explain your answer.     A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas…

Read it carefully and answer the question add the bottom please?

help please

I have attached the picture for review. Please answer section A, B, C.

iris is a built-in R data set (data frame). This data set contains gives the measurements in centimeters of the variables sepal length and width and petal length and width, respectively, for 50 flowers from each of 3 species of iris. The species are Iris setosa, versicolor, and virginica. We are interested in some descriptive statistics related to the Sepal.Width column of the data frame. We can access the data directly by using the assignment x <- iris$Sepal.Width (In R use ?iris for info on this dataset.)Remember: x <- iris$Sepal.Widtha.Calculate the sample median of x. b. Using the R quantile function, find the .80 quantile of x.(80th percentile) c. Calculate the interquartile range of x using R. d. Calculate the sample mean of x. e. Calculate a 4% trimmed mean for x. f. Calculate the sample variance of x. g. Calculate the sample standard deviation of x. h. What proportion of the x values are within 2.0 sample standard deviations from the sample mean i. Calculate the minimum…
