A teacher wants to find out the average number of weekly reading hours of her students. She noted the number of reading hours of 5 of her students, as shown below:
5, 2, 4, 8, 6
Which measure of central tendency is most appropriate for this situation, and what is its value? (5 points)
Only the median; 5
Only the mean; 4
Either the mean or median; both are 5
Either the mean or median; both are 4
I dont know the 3rd one can any one help
This is a little absurd
ur supost to answer the questeon
acording to my calculations your not very inteligent (snort) nerd emoji
sorry it dident let me put the url
1. The statistical question in the survey is "How many class projects did you complete using the computer lab?" This is a statistical question because it involves collecting data about the number of class projects completed, which can vary from student to student.
2. Bill wrote a statistical question because there can be many answers to the question "How many books were recommended by the book reading club this month?" This question involves collecting data on the number of recommended books, which can vary each month.
3. It cannot be determined what the writing score of each student would be if all the students scored the same. The question asks for the writing score of each student, but the information given in the question does not provide enough data to determine the exact score.
4. The mean height of the students in the group is 46 inches. To find the mean, you add up all the heights and divide by the total number of students. The sum of the heights (49 + 48 + 41 + 45 + 47) is 230, and there are 5 students, so the mean is 230/5 = 46 inches.
5. The shape of the data in the dot plot is described as symmetric and has no gaps. In a symmetric distribution, the data is evenly distributed around the center, and there are no gaps in the data.
6. The plot that represents the data in the table is: A line with 4 tick marks labeled Cat, Dog, Rabbit, and Guinea Pig. Cat has 5 crosses, Dog has 3 crosses, Rabbit has 1 cross, and Guinea Pig has 3 crosses. The line is labeled Number of Pets, and the title of the graph is Pet Owners.
7. The data table that accurately represents the data in the histogram is: Age Group - Number of People, 18-24 - 80, 25-31 - 120, 32-38 - 40, 39-45 - 20. This table matches the age groups and the corresponding number of people in each group as shown in the histogram.
8. The box plot that represents the data is: A box and whisker plot drawn using a number line from 20 to 35. The box extends from 21 to 28, with a vertical line at 26. The whiskers end at 20 and 29. This plot accurately represents the minimum, maximum, median, and quartiles of the data set.
9. The information not provided in the histogram is the number of students who collected exactly 2 bottles. The histogram only provides information about the ranges of the number of bottles collected, not the exact values.
10. At least 8 schools have participated for more than 1 year and less than 6 years. To find this, we look at the box plot and see that the box extends from 1 to 6 on the number line, which represents the range of years. We can infer that at least 8 schools fall within this range.
11. Based on the data set, there are no outliers. An outlier is a value that is significantly different from other values in the data set. In this case, all the values in the data set are within a reasonable range and there are no extreme values.
12. The most appropriate measure of central tendency for this situation is the mean, and its value is 5. To find the mean, you add up all the reading hours (5 + 2 + 4 + 8 + 6) and divide by the total number of students (5), which gives you an average of 5 hours.
Don't know if anybody would just do this assignment for you and
rob you of the joy and feeling of satisfaction one gets of learning
a new topic and getting the answers all by yourself.
Besides, just giving you the answers would be cheating, and you wouldn't
do that now, would you ??
