Answer:
The relevant probability is P(56 or more girls).
56 girls in 100 births is not a significantly high number of girls.
Step-by-step explanation:
To evaluate if 56 girls in 100 births a significantly high number of girls we must look at the cumulative probability of 56 girls or more in 100 births (P(n≥56)=0.136). The probability of exactly 56 girls is not particularly relevant since it represents only 1 of 100 possible outcomes and thus its likelihood is quite low, the higher the number of outcomes the less significant the probability of a single outcome occurring becomes.
Since the relevant probability is higher than 0.05, (0.136 > 0.05), 56 girls in 100 births is not a significantly high number of girls.
