A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below. Studied: 87 100 94 79 92 100 95 83 89 99 100 91 89 95 100 93 96 83

Did Not Study: Nobody cares

Brainliest
Part 1: Calculate the mean absolute deviation of the group that studied, rounded to the nearest tenth.

Part 2: How many of the scores (from the group that studied) are within one mean absolute deviation of the mean

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly
