Find the median of the following data set. Assume the data set is a sample. \[ 34,41,42,47,30,42,43,36,40,37,37 \]

A researcher rejects the null hypothesis only if the obtained statistical results show: that it is likely that the null is true. that it is unlikely that the null is true. that it is likely that the alternative hypothesis is false. that is unlikely that the alternative hypothesis is false.

The estimated standard error (SM), provides a measure of the average discrepancy between: a score ( x ) and the population mean ( \( \mu \) ). a sample mean (M) and the population mean ( \( \mu \) ). the sample standard deviation ( s ) and the population standard deviation ( \( (\mathrm{O} \) ).

By selecting a smaller alpha level, a researcher is: attempting to make it easier to reject the null (HO). attempting to make it easier to reject the alternative (H1). reducing the risk of a Type I error. attempting to decrease the standard error.

The null hypothesis: predicts that the treatment will have no effect. predicts that the treatment will have an effect. is denoted by the symbol H1. is always stated in terms of sample statistics.

A design that has two conditions (treatments) with the same participants experiencing each condition is a(n): two independent groups design. repeated measures design. Analysis of Variance (ANOVA) design. single sample t test design. single sample Z test design.
