a. What is the average price for the phones (to 2 decimals)?

b. What is the average talk time for the phones (to 3 decimals) in hours?

c. What percentage of the phones have a voice quality of excellent (to the nearest whole number)?

Answer :

Final answer:

The average price of the phones is 68.13. The average talk time of the phones is 72.500 hours. 25% of the phones have a voice quality of 'excellent'.

Explanation:

To find the average price for the phones, we would add up the prices of all the phones and then divide by the total number of phones. Prices: 60 + 80 + 100 + 70 + 45 + 80 + 60 + 50 = 545. The average price is 545 divided by 8 (total number of phones) which gives us 68.125. Thus, the average is 68.13 (rounded to 2 decimal places).

To get the average talk time, the same method is used but this time with the talk times: 73 + 70 + 78 + 72 + 70 + 73 + 72 + 72 = 580. Dividing 580 by 8 gives us 72.5, rounded off to three decimal places, the average talk time is 72.500 hours.

To find out what percentage of the phones have a voice quality of 'excellent', we note how many phones are rated as 'excellent': 2 out of 8. Therefore, 2 divided by 8, multiplied by 100 gives us 25%. Thus, 25% of the phones have a voice quality rating of 'excellent'.
