Document Summary

Confidence intervals 3 z ci for p. An educator is trying to tailor her course materials to student needs. She is concerned about using certain colors in her materials, in case there is a high frequency of students with red-green colour blindness. What type of data (measurement) would you be collecting for the educator"s study of red-green colour blindness: nominal, ordinal. What statistic would you use to summarize the sample data collected for the educator"s study of red-green colour blindness: mean, standard deviation, proportion, more than one of the above. Can not calculate means or standard deviation of words. Only way to summarize qualitative data is proportion. You want to calculate the probability that at least 4 out of a srs of n=8 students in the educator"s course display red-green colour blindness. Previous research suggests the 10% of the general student population displays red-green colour blindness.
