Is the estimated coefficient of the price of pizza statistically significant at the 5% level? You can use either the t-test or the P-value, not both since both gives the same results (read my lecture note on testing hypothesis). What does it mean when you reject the null hypothesis?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

its less than 713.21 but greater than 5.2
