Some data sets include values so high or so low that they seem to stand apart from the rest of the data. These data are called outliers. Outliers may represent data collection errors, data entry errors, or simply valid but unusual data values. It is important to identify outliers in the data set and examine the outliers carefully to determine if they are in error. One way to detect outliers is to use a box-and-whisker plot. Data values that fall beyond the limits Lower limit: Q1 − 1.5 ✕ (IQR)Upper limit: Q3 + 1.5 ✕ (IQR) where IQR is the interquartile range, are suspected outliers. In the computer software package Minitab, values beyond these limits are plotted with asterisks (*). Students from a statistics class were asked to record their heights in inches. The heights (as recorded) were as follows. 65 72 68 64 60 55 73 71 52 63 61 74 69 67 74 50 4 75 67 62 66 80 64 65 (a) Find the value of the interquartile range (IQR).IQR = (b) Multiply the IQR by 1.5 and find the lower…
Flavia wanted to know if the first sample quartile (or Q1) was an unbiased estimator of the first population quartile. She started with a large population of normally distributed grades, the first quartile of which was Q = 70. She then took a random sample of 6 tests and calculated the first quartile of the sample. She replaced those exams and repeated this process a total of 50 times. Her results are summarized in the dot plot below, where each point represents the first sample quartile of a sample of 6 exams. Based on these results, does the first sample quartile appear to be a biased or unbiased estimator of the first population quartile? Track; the first population quartile is 70.

Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 232 feet and a standard deviation of 52 feet. We randomly sample 49 fly balls. I need help solving the problems below What's the probability that the 49 balls traveled an average of less than 224 feet? (answer must be rounded to four decimal places) Sketch the graph. Scale the horizontal axis for x̅. and shade the region corresponding to the probability Find the 70th percentile of the distribution of the average of 49 fly balls. (answer must be rounded to two decimal places) Can you please show me your work so I can understand and learn how you got the answer Thank you
While performing searches on the Internet to find accommodation, Jasmine realized that the cost of a housing unit seems to be related to the number of inhabitants of the municipality where the unit is located. She noted the following data. She represented the data in a scatter plot, where she drew a line of best fit passing through the mean point of the distribution. If Jasmine considers that a linear correlation exists between these two variables, what should be the mean monthly rent of a 4½-room unit in a municipality with a population of approximately 250 000? Justify your answer algebraically.
How do I complete this? Any help would be great and useful
True or False. The standard deviation of the mean is less than the sample standard deviation because it estimates the variation of averages, which are more precise than single observations.
What does the "box" of a box-and-whisker plot encompass? Outliers None of these Minimum and maximum Q1, Q2, Q3
Provide answer.
2. What does it mean for a scatter plot to have a negative trend? O A. Higher c-values tend to go with higher y-values. OB. Higher -values tend to go with lower y-values. OC. The x- and y-values appear to be unrelated. OD. None of these are true.
5. Which of the following is the assumption that the best way to describe the pattern of data is using a straight line? homoscedasticity normality linearity restriction of range
