According to the US
Bureau of Labor Statistics,
Data
The data can be found
at stat.hawkeslearning.
com Data Sets > Employee
Satisfaction.
there was a 12.4%
incidence of workplace
injury in 2016 in the private sector. If the workplace
accident rate is above 12.4% , the company will
increase inspections and implement additional
safety training. For this data, is there statistical
support to increase inspections and implement
additional safety training? Use the entire dataset
and the work accident variable where 0 = no accident
and 1= an accident occurred.
1. Is work accident a qualitative or
quantitative variable?
2. Graph the accident at work data with an
appropriate graph and calculate statistics
appropriate for this type of data.
3. Conduct the appropriate hypothesis test using
the following steps.
a. Determine the null and alternative
hypotheses.
b. Use a significance level of a = 0.05.
c. Validate the assumptions of the hypothesis
test, identify the appropriate test statistic,
and compute its value.
d.
Determine the P-value.
e. Make a decision to reject or fail to reject H
f. State the conclusion in terms of the
original problem.
4. Based on our conclusion from the previous
step, what type of error could we have just
made (Type I or Type II)? State the practical
implications of this error
