Can someone help me with these.

Use the given data values​ (a sample of female arm circumferences in​ centimeters) to identify the corresponding z scores that are used for a normal quantile​ plot, then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile​ plot, then determine whether the data appear to be from a population with a normal distribution. 33.9​, 37.9​, 43.8​, 32.8​, 40.1 Question content area bottom Part 1 List the z scores for the normal quantile plot.   Part A -List the z scores for the normal quantile plot.     Part B- Identify the coordinates of each point in the normal quantile plot. Use ordered pairs for the form​ (x,y), where x is the sorted arm circumferences in ascending​ order, and y is the corresponding z score.   Part C- Do the data come from a normally distributed​ population?

1. The two plots have similar distrubutions. Are the distrubutions skewed left, approximtly symmetric, or skewed right? 2. Which is greater, the mean or the median, within each plot? Why does this make snese, gicen the type of distrubution you identified in the first part? 3. The population has drastically declined over recent years. Does the data show a difference in bee prefrence towards high quality hives versus how quality hives? Usse statistical evidennce to support your response.

A large, multi-company construction workers union is gathering data on the number of workplace injuries that occurred last year. It gathers the number of injuries from 20 randomly selected companies among the hundreds of construction companies at which its members work. The data are provided below. Use Excel and the QUARTILE.INC function to construct a box and whisker plot for the dataset. What is the value of the median? Round your answer to one decimal place. Number of on the job injuries 133333220324312076417 109328 30

Use the dot plots to complete the following. 6. 10 Class A Class E The shape of the distribution for Class A İS (type skewed or symmetric): The shape of the distribution for Class B is (type skewed or symmetriCH When comparing the distributions for Class A and Class 3 the apprcoriate numoer summary T should use for the center is (type mean or median): When comparing the distributions for Class A and Class B the appropriate number summary Ishould use for the varlation is (type standard deviation or IQR):

A uniform distribution has endpoints 4 and 18. What is the 90th percentile, reporting to one decimal place?

10. Consider the box plot shown below: 2 4 6 8 10 12 14 16 a. What is the median of the data set? b. What are the upper and lower quartiles of the dataset? c. What is the interquartile range of the dataset? d. Is the data set skewed to the left, skewed to the right, of symmetric? e. What percentage of the observations in the data set lie to the right of the median? To the left of the upper quartile?

What is the slope of the median median line for the dataset in this table?
