Question
A research study wishes to examine the mean resting heart rate for 16 individuals among four different groups of exercises (evenly distributed to 4 individuals per group). What type of test statistic do you need to run for this type of analysis? Select one: a. Chi-Square Test of Independence b. Chi-Square Goodness of Fit c. Z-test d. T-test e. F-test
2% of mosquitos caught at random in any given field study carry malaria. If you conduct a study and capture 19 mosquitos, how many mosquitos infected with malaria would you expect to have in your mosquito-catching Mason jar out of all 19 mosquitos buzzing around? Round up to the nearest whole number if your calculation results in a number with decimal point values. For example, 0.2 rounds up to 1 and 74.25 rounds up to 75.
Explanation / Answer
Answer - 1: Since we need to compare the mean of more than two groups, we will use F - test
Answer - 2: Expected number of Malaria mosquitos = 19*0.02 = 0.38 = 1
