You estimate that the proportion of viable hybrid offspring from this female is and the $95 \%$ confidence interval for is $0.40-0.65$. Based on these results, would you conclude that hybrid offspring from this fly are less viable than offspring from typical crosses within species? [1 point]

Answer

It is not possible to conclude that hybrid offspring from this fly are less viable than offspring from typical crosses within species based solely on the provided confidence interval.

Solution

a

Confidence Interval Interpretation: The provided confidence interval of $0.40-0.65$ indicates that there is a 95% chance that the true proportion of viable hybrid offspring falls within this range

b

Comparison with Typical Crosses: To determine if hybrid offspring are less viable, we would need data on the proportion of viable offspring from typical crosses within species for comparison

c

Statistical Significance: Without a point of comparison or additional statistical analysis, we cannot conclude that the viability of hybrid offspring is significantly different from that of typical crosses

Key Concept

Confidence intervals provide a range in which the true value is likely to fall, but they do not alone allow for comparisons or conclusions without additional data.

Explanation

The confidence interval gives an estimate of viability but does not provide evidence of lower viability compared to typical crosses without a known proportion of viable offspring from within-species crosses for comparison.
