Answer:
Hence the study seem to be inconclusive since the probability of getting those result by chance are somewhat very high.
Step-by-step explanation:
The result seem to be inconclusive since the probability of getting those result by chance are somewhat very high.
Since the probability of getting such sample result by chance are very high, we cannot assume that the women have the ability to predict the gender of their babies.
Hence the study seem to be inconclusive since the probability of getting those result by chance are somewhat very high
The z-value that corresponds to a two-tailed 95% confidence interval is z = +/- 1.96. Then the bounds of the confidence interval can be determined as:
Lower bound = mean - z*SD/sqrt(n) = 20 - 1.96*2/sqrt(100) = 20 - 0.12 = 19.88 hours
Upper bound = mean + z*SD/sqrt(n) = 20 + 1.96*2/sqrt(100) = 20 + 0.12 = 20.12 hours
So the first choice is the correct answer: 19.88-20.12 hours
