Is Meat Consumption Age dependent ?
What is the best prediction for Meat Consumption of a 50 years old Male ?
We want to investigate if Age is Gender dependent, BUT we want to do it using a Contingency Analysis!
What is your expectation for the p-value ?
Can you compute a Confidence Interval for Meat Consumption mean value (μ) ?
Still about the model considered in the previous Question:
The OLS estimates were computed with the sample:
Based only on this analysis what would your conclusions be, regarding the impact of Age in WP, using any common level of significance ?
Check this new model
The OLS estimates were computed with the sample
The ε assumptions were checked and seem to be met.
If you consider α=0.01 there is a contradiction between the conclusion regarding Ho:R2=0 and Ho:βi=0.
What would you do next to clarify this contradiction ?
I would run
NetfilxU was added to the previous model:
Using the same sample (n=22), these OLS estimates were computed
What are your conclusions using a 0.10 level of significance ?
This model
was estimated:
It seems to be true that, if α=0.10,
The coefficient of correlation between WP and Income, computed with the sample (n=22), is 0.436
Is this model
significant (α=0.10) ?
Still about this model
with the same sample (r=0.436), OLS β1 estimate was found to be
