In a small-scale regression study, five observations on Y were obtained corresponding to X = 1, 4, 10, 11, 14. Assume that σ = 0.6, β0 = 5, and β1 = 3.(a) What are the expected values of MSR and MSE here?(b) For determining whether or not a regression relation exists, would it have been better or worse to have made the five observations ad X = 6, 7, 8, 9, 10? Why? Would the same answer apply if the principal purpose were to estimate the mean response for X = 8? Discuss.

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

ok so what's the question?

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
