Question

Transcribed Image Text:Researchers claim that the surface temperature of the world's oceans mainly changes with
changing latitude. The warmest waters are near the equator and the coldest waters are in the
Arctic and Antarctic regions. To examine this claim, an experiment has been designed and the
following data has been collected from coastal areas in the southern hemisphere for 5
consecutive years in the middle of November. The recorded temperatures are all averages
across the 5 years of data.

Note: Temperature.xlsx is also attached.
a) Convert the latitude numerical variable to a categorical variable with 4 levels (very low,
low, moderate, high), using a statistical software package. Find the overall mean, group
means, and group standard deviations using the statistical package. Conduct an ANOVA
test to find the possible impact of latitude on coastal ocean surface temperature. Write
the assumptions of the model, write out the model in cell means/classical/regression
form, conduct the analysis in a statistical software package, run the Tukey HSD test if
needed, and state a conclusion based on the output.
