The dot plot shows how many attempts it took for each student to complete a puzzle:

Is the median or the mean a better measure of center for these data and why?

Mean, because the data are skewed and there are outliers

Mean, because the data are symmetric and there are no outliers

Median, because the data are skewed and there are outliers

Median, because the data are symmetric and there are no outliers

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Arandomized controlled trial is designed to evaluate the effect of metoprolol in patients with heart failure. while preparing for statistical analysis, the researcher reviews some common types of statistical errors. which of the following statements is true regarding a type i error in a clinical study? a. the study is not significantly powered to detect a true difference between study groups. bthe null hypothesis is true but is rejected in error. c. the null hypothesis is false but is accepted in error. d. type i error is also known as beta and is usually 0.1 or 0.2. e. type i error depends on the study's confidence interval.

Point b lies between points a and c on . let x represent the length of segment ab in inches. use the segment to complete the statements. the value of x is . the length of in inches is . the length of in inches is .
