Answer from: NateTheBeast12

Step-by-step explanation:

To calculate the 99th percentile you must order scores from least to greatest, and the one that occupies the position that corresponds to 99% of n-scores is the 99th percentile.

The 99th percentile of a set of observations ( in this case, exam scores) is a value such that 99% of the observations are less than or equal to him and the remaining 1% is greater than or equal to him.

If he is now in the 84% is because there are some people that took the exam in February that are better than him, they had better scores and then, 84% of the observations are less than or equal to him and the remaining 16% is greater than or equal to him.

Before there were only 1% scores that were better than his or her score. Now, there are 16% scores that are better, then people got better scores in the February exam, compared to your friend's score.

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.

Acell phone company offers two plans to its subscribers. at the time new subscribers sign up, they are asked to provide some demographic information. the mean yearly income for a sample of 40 subscribers to plan a is $45,000 with a standard deviation of $9,200. for a sample of 25 subscribers to plan b, the mean income is $64,300 with a standard deviation of $7,100. at the 0.025 significance level, is it reasonable to conclude the mean income of those selecting plan b is larger? assume unequal population standard deviations. hint: for the calculations, assume the plan a as the first sample. what is the decision rule?
