3.Using a Shapiro-Wilks normality test, decide whether you can accept or reject the assumption of normality of a parametric test with the hiv.csv data from the lab test exercise and an alpha of 0.05.

Select one:

a. Reject

b. Accept

Answer #1

With your newly-developed statistical tools, you decide
to put this hypothesis to the test. You know that the standard
intelligence quotient (IQ) score has a population mean of 100 with
a standard deviation of 15. You find that a random sample of 121
Lakers fans has an average IQ score of 103. Use this evidence to
test your roommate’s argument that Lakers fans are more intelligent
than the general population.

On your first day on the job, your boss asks you to conduct a
hypothesis test about the mean dwell time of a new type of UAV.
Before you arrived, an experiment was conducted on n= 5 UAVs (all
of the new type) resulting in a sample mean dwell time of y-bar=
9.4 ℎours. The goal is to conclusively demonstrate, if possible,
that the data supports the manufacturer’s claim that the mean dwell
time is greater than 10 hours. Given...

Recently, research suggested that eating eggs is again
considered potentially bad for your heart health. You are part of a
team that did a healthy diet information talk to 50 students
randomly chosen at the University of Arizona. After a year, you
surveyed the same 50 people to find out if the average number of
eggs eaten was significantly less than the US average of 1.7 per
week. The sample mean was 1.5 eggs/week and sample standard
deviation was 0.3...

Recall in our discussion of the normal distribution the research
study that examined the blood vitamin D levels of the entire US
population of landscape gardeners. The intent of this large-scale
and comprehensive study was to characterize fully this population
of landscapers as normally distributed with a corresponding
population mean and standard deviation, which were determined from
the data collection of the entire population.
Suppose you are now in a different reality in which this study
never took place though...
