\( \begin{array}{l}\text { An allele can be favorable in one environment (compared to } \\ \text { the other alleles) but unfavorable in a different environment } \\ \text { (compared to these same alleles). }\end{array} \) False

For the function below, write the differential. \[ f(x)=\ln \left(1+x^{2}\right) \] \( d y=\left(\frac{2 x}{1+x^{2}}\right. \) Calculate \( d y \) for the given values of \( x \) and \( d x \). \[ x=2 \text { and } d x=0.2 \] \( d y=016 \) How accurate is \( d y \) in approximating \( \Delta y \) (1.e., what is their difference) to the nearest thousandth?

What is the value of \( z^{*} \) for \( 98 \% \) confidence? 1.645 2.576 2.326 1.960

2) Choose the best answer. Mr. Martinez wants to plan a skiing trip 500 miles from his home. If a thirty minute stop will be taken for lunch, and the average speed will be 60 miles per hour, about how long will the trip take?

Do all three of these interpretations give "confidence" rather than "probability?" yes no

A \( 90 \% \) confidence interval for \( \mu \) is \( (11.5,12.3) \). What is the probability that the value of \( \mu \) is in this interval? 0.90 zero or one-we just don't know which
