Researchers claim that the surface temperature of the world's oceans mainly changes withchanging latitude. The warmest waters are near the equator and the coldest waters are in theArctic and Antarctic regions. To examine this claim, an experiment has been designed and thefollowing data has been collected from coastal areas in the southern hemisphere for 5consecutive years in the middle of November. The recorded temperatures are all averagesacross the 5 years of data.Coastal oceanSurfaceTemperatureLatitude4442403836343230282624222018161412108614.115.216.217.5182122.123.824.524.224.42626.928.228.528.829.829.831.232.5Coastal AirTemperature1617151518.52224.5242526.53031.630.433.533323233.53430Note: Temperature.xlsx is also attached.You can copy and paste on the portal this question A to d.Is solved only e is missinge) Run this two-way ANOVA design and state your conclusion.
