You shop for bikes and find 7 types priced at 119 139 149 179 189 199 and 209. you want to buy the 189 bike would you use the mean median and mode to convince your parents that this is a reasonable price for a bike? explain
Please help me
Median = middle price
Mean = average price
Mode = most common price (Note: these data have no mode.)
I'll be glad to check your answers.
189 is above the median and there is no mode.. so I would think you want to use the mean.
However, you need to average those 7 prices and see if the average is 189 or less,
Thank you Ms.sue and Anonymous!
do i need to close this or something?
No. If you have your answer, you need do nothing more. In addition, you've thanked us, which usually signals a close.
Ok Thanks
To convince your parents that the price of $189 for a bike is reasonable, you can use the mean, median, and mode of the prices of the 7 types of bikes. Here's how you would calculate each of these measures and explain their significance:
1. Mean: The mean is calculated by adding up all the prices and dividing the sum by the number of prices. In this case, you would add up all the prices:
119 + 139 + 149 + 179 + 189 + 199 + 209 = 1183
Then, divide the sum by the number of prices (which is 7 in this case):
1183 / 7 = 169
The mean price of the bikes is $169. Since the price of $189 is higher than the mean, you can argue that it is reasonable because it falls within the range of prices.
2. Median: The median is the middle value of a set of numbers when they are arranged in ascending or descending order. In this case, you would arrange the prices in ascending order:
119, 139, 149, 179, 189, 199, 209
Since there are 7 prices, the middle value is the fourth one, which is 179. Since the price of $189 is higher than the median, you can argue that it is reasonable as it is closer to the higher end of the distribution.
3. Mode: The mode is the value that appears most frequently in a set of numbers. In this case, there is no mode since no price is repeated more than once.
By considering the mean, median, and mode, you can explain to your parents that the price of $189 for the bike is reasonable because it is higher than the mean and the median, indicating that it is within the range of prices and closer to the higher end of the distribution.
