Chapter 4 Quiz Prevlous 3 4 5 6 78 9 10 Noxt Question 4 of 18 (1 point) In a survey 46,212 women were asked how many children they had. The results were as follows. Number of Women 12,598 7,474 11,262 7,043 3,790 1,819 922 528 776 46,212 Number of Children 5 8 or more Total What is the probability that a sampled woman has seven children? The probability that a sampled woman has seven children is What is the probability that a sampled woman has fewer than two children? a. b. The probability that a sampled woman has fewer than two children is e. Assume this is a simple random sample of U.s. women. Use the Empirical Method to estimate the probability that a woman has more than five children. The probability that a woman has more than five children is approximately

Explanation / Answer

(a) here total women are =46212 and

number of women who have 7 children=528

probability that sampled women has a seven children=528/46212=0.0114

(b) fewer than 2 children means women with 0 or 1 children and this is =12598+5474=18072

required probability that a sampled women has fewer than 2 children=18072/46212=0.3911

(c) number of women having more than 5 children means woman has either 6 or 7 or more than 8 children

i.e. 922+528+776=2226

and required probability=2226/46212=0.0482
