Using traditional methods, it takes 94 hours to receive a basic flying license. a new license training method using computer aided instruction (cai) has been proposed. a researcher used the technique with 80 students and observed that they had a mean of 92 hours. assume the standard deviation is known to be 6. a level of significance of .05 will be used to determine if the technique performs differently than the traditional method. is there sufficient evidence to support the claim that the technique performs differently than the traditional method? perform a hypothesis test. show diagram

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230

introduction, methodology, results, discussion

step-by-step explanation:

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

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

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

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
