A business manager in a health-care facility has been
investigating the cost of maintaining patients within its plan. A
sample of 20 cases for the last month reported the following: 1
$1,168.00 5 $1,165.00 9 $1,125.00 13 $1,324.00 17 $1,179.00 2
$1,225.00 6 $1,345.00 10 $1,276.00 14 $1,445.00 18 $1,253.00 3
$1,195.00 7 $1,240.00 11 $1,423.00 15 $1,345.00 19 $1,435.00 4
$1,054.00 8 $1,187.00 12 $1,239.00 16 $1,186.00 20 $1,252.00
What is Hypothesis?
In the context of the problem in Q1 (health care facility), describe any one research problem and the related hypothesis to be tested; remember to identify the null and alternate hypothesis

What is Hypothesis?
Hypothesis is a way of statistical investigation wherein some explanations are made based on previous observations. Evidences are collected and tested and then final conclusions are made with some probabilities. These conclusions are made about the population parameters.
In the context of the problem in Q1 (health care facility), describe any one research problem and the related hypothesis to be tested; remember to identify the null and alternate hypothesis
We can conduct hypothesis for concluding about the population means or standard deviations or comparisons.
In our context, we can test for the health care cost to be tested against the claim that previously the mean cost was about $1000. Due to inflation, there is also an increase in the cost of living and the health care. We have to test whether the cost of care has actually increased or not. That is whether the inflation affected the health care or not.
(the cost is $1000 or less than $1000)
VS
(the cost is more than $1000)
