Question

2 of 16 (2 complete) Hw Score: 8.33%, 1.33 of 16 pts Score: 0.33 of 1 pt %)5.1.4 For 100 births, P(exactly 57 girls) 0.0301 and P(57 or more girls) 0.097. Is 57 girls in 100 births a significantly high number of girls? Which probability is relevant to answering that question? Consider a Question Help number of girls to be significantly high if the appropriate probability is 0.05 or less. The relevant probability is | so 57 girls in 100 births | | a significantly high number of girls because the relevant probability is 0.05.

Explanation / Answer

To check the unusual numbers, we always find the total probability to its right or left depending on whether the point is unusually high or low.

Hence,

The relavant probability is P(57 or more girls) so 57 girls in 100 births is not a significantly high number because the relavant probability is greater than 0.05.
