Question

a group of random people were polled about whether they prefer to communicate using text messages or by phone calls. the results are shown in the conditional relative frequency table by row.

	text	call	total
female	0.46	0.54	1.00
total	0.50	0.50	1.00

what is the probability of someone preferring phone calls, given the person is a female?
43%
46%
54%
57%

Explanation:

Step1: Identify relevant value

In the conditional - relative frequency table by row, the row for females shows the relative frequencies of communication preferences. The value corresponding to females who prefer phone calls is 0.54.

Step2: Convert to percentage

To convert the decimal 0.54 to a percentage, we multiply by 100. So, \(0.54\times100 = 54\%\).

Answer:

54%
