Many people want to increase their protein intake, but are they sacrificing higher fat content?

Perform a hypothesis test at a 95% significance level to determine if higher fat is associated with

higher protein levels. Clearly state all the steps of a hypothesis test. Use the following output.

Coefficients:

Estimate Std.Error t value Pr(>|t|)

Intercept: 5.9775 1.9821 3.016 0.0035 **

fat: 0.2545 0.1282 1.986 0.0507

Additionally, A) How to find the t critical value from this question? and B) what does Pr(>|t|) mean?

please provide well-organized explanation step by step precisely
