The data shown below represents the age (in weeks) at which babies first crawl, based on a survey of 12 mothers.Data: 52, 30, 44, 35, 47, 37, 56, 26, 37, 36, 52, 37(a) Draw a normal probability plot to determine if it is reasonable to conclude the data come from a population that is normally distributed. Choose the correct answer below.Options:- A. A plot showing a linear pattern where expected z-scores and age (in weeks) increase together.- B. A plot showing a minor deviation from linearity.- C. A plot showing a strong linear pattern suggesting normality.- D. A plot with noticeable deviation from linearity.Since the correlation between the expected z-scores and the observed data is \( \_\_\_\_ \), \( \_\_\_\_\_\_\_\_\_\_ \) the critical value, it \( \_\_\_\_\_\_\_\_\_\_ \) reasonable to conclude that the data come from a population that is normally distributed. *(Round to three decimal places as needed.)*(b) Draw a boxplot to check for outliers. Choose the correct answer below.Options:- A. A boxplot displaying no apparent outliers.- B. A boxplot with an indication of potential outliers.- C. A symmetric boxplot with extremes within normal range.- D. A boxplot with skewness showing possible outliers.Does the boxplot suggest that there are outliers?If no: There are no points that are greater than the third quartile or less than the first quartile.

O Macmillan Learning The domestic cat, Felis catus, is a domesticated furry creature often kept as a pet in many countries. Suppose a volunteer at a local animal shelter wanted to find out a little more about the cats in her care. The volunteer carefully measured the height for the 10 fully grown adult cats at her shelter. The height measurements were taken from the base of the foreleg to the shoulder. The table shows the results of the measurements. Calculate the mean, variance, and standard deviations for cat height for the sample of shelter cats. Report all your answers to two decimal points. mean: variance: standard deviation: in in² in Sample 1 2 3 4 5 6 7 8 9 10 Height (in) 10.5 13 7.7 7.5 9.55 10.5 10.85 12.3 8.15 7.85
