Please, please i really need help with these questions please direct me towards the right answer
well im not asking you to give me the answer i just need help to be going to the direction of the problem that's all but im not asking for the answer
1. The best type of graph to illustrate differences in data by using bars to represent the data is (a) bar graph.
2. To calculate the mean, median, and mode of the sales made last year, you need to calculate the average, find the middle value, and determine the most frequently occurring range. Based on the given data, the correct answer is (a) mean: $99,231.27; median: $90,001-110,000; mode: $90,001-110,000.
3. The best type of graph to present a progression in historical data is (b) line graph.
4. The most useful type of graph for illustrating how data are divided is (c) circle graph.
5. To find the standard deviation when the variance is given, you take the square root of the variance. Based on the given variance of 49, the correct answer is (b) 7.
6. If the housing budget is 25% of total expenses, it would be represented by (c) 180° on a circle graph.
7. To find the average rate of return for six different stocks, you need to calculate the average of the given rates. Based on the given data, the correct answer is (b) 6.417%.
8. Approximately 99% of all values will fall within (e) 3 standard deviations in a normal distribution.
9. Graphs make visual the relationship between the sets of data. The correct answer is (b) Graphs.
10. A normal distribution is also called a (b) bell curve.
Sure! I'll guide you through each question and explain how to find the right answer.
1. Which type of graph is best to illustrate differences in data by using bars to represent the data?
To answer this question, you need to know the types of graphs and their characteristics. A bar graph is the most suitable option for illustrating differences in data using bars. So, the correct answer is (a) bar graph.
2. Sales made last year by Murray's Appliance Store are listed below. Calculate the mean, median, and mode.
To find the mean, you need to calculate the average of all the sales amounts. Add up the amounts and divide by the total number of sales employees.
To find the median, you need to arrange the sales amounts in ascending order and find the middle value. If there is an even number of values, take the average of the two middle values.
To find the mode, you need to identify the value that appears most frequently in the sales amounts.
Once you perform these calculations, you can match the values with the options provided to find the correct answer.
3. Which type of graph is best used to present a progression in historical data?
To answer this question, you need to understand the characteristics of different types of graphs. A line graph is typically the best choice for presenting a progression in historical data, as it shows the trend over time. So, the correct answer is (b) line graph.
4. Which type of graph is the most useful for illustrating how data are divided?
To answer this question, think about the purpose of each type of graph. A pie chart is the most useful for illustrating how data are divided because it displays the proportion of different categories or parts in relation to the whole. So, the correct answer is (c) circle graph (pie chart).
5. If the variance is 49, what is the standard deviation?
The standard deviation is the square root of the variance. So, you need to calculate the square root of 49. Once you calculate it, match the value with the options provided to find the correct answer.
6. If the housing budget is 25% of total expenses, how many degrees on a circle graph would this be?
A circle graph represents 100% of the data. To find the number of degrees for 25%, multiply 25 by 3.6 (since 360 degrees represent 100%). So, the correct answer is (b) 90°.
7. Find the average rate of return for six different stocks.
To find the average rate of return, add up the rates of return for all six stocks and divide by the total number of stocks. Once you calculate it, match the value with the options provided to find the correct answer.
8. Approximately 99% of all values will fall within __________ standard deviations in a normal distribution.
In a normal distribution, approximately 99% of all values fall within 3 standard deviations from the mean. So, the correct answer is (e) 3.
9. __________ make visual the relationship between the sets of data.
To answer this question, you need to understand the different terms and their definitions. Graphs are used to make visual the relationship between sets of data. So, the correct answer is (b) Graphs.
10. A normal distribution is also called a(n)_________.
A normal distribution is also called a bell curve because of its shape resembling a bell. So, the correct answer is (b) bell curve.
I hope this helps you find the right answers to the questions!
