More critical values For each of the following situations, find the critical value for z or t.
a) H0: μ = 105 vs. HA: μ ≠ 105 at α = 0.05; n = 61.
b) H0: p = 0.05 vs. HA: p > 0.05 at α = 0.05.

- In a study of how students give directions, forty volunteers were given the task ofexplaining to another person how to reach a destination. Researchers measured thefollowing five aspects of the subjects’ direction-giving behavior:• whether a map was available or if directions were given from memory without a map,• the gender of the direction-giver,• the distances given as part of the directions,• the number of times directions such as “north” or “left” were used,• the frequency of errors in directions. Identify each of the variables in this study, and whether each is quantitative orqualitative. For each quantitative variable, state whether it is discrete or continuous. Was this an observational study or an experimental study?
