John gets a raise and decides to start buying enriched pasta instead of cheaper instant noodles. For John, instant noodles are examples of
A.inelastically
B.complements
C.market demand
D.inferior goods

For John, instant noodles are examples of

D.inferior goods

Explanation:

John treats instant noodles as cheaper goods and only is buying them because he has no choice but to buy them at that time.

Thus in his mind they are inferior goods to what he can buy when he has more money.

This concept could arise due to the brand marketing or the taste of the food or the simple marketing of it

The brands like that are marketed as cheap food so they are also being treated as such by the people who buy them as they understand the function of it as such.

a. 2.13. b. (30.53, 34.79). c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.

Explanation:

The size of the sample is 42 and the mean of the sample is ∑ = 32.66 and the standard deviation of the sample (σ) is √[∑(-μ)^2 - 1] = √46.6092 = 6.8271

a. α = 1 - (95/100) = 0.05; α/2 = 0.025; the degree of freedom = n-1 = 42-1 = 41; tα/2 = t0.025 = 2.02. Thus, the error margin = (tα/2)*(σ/√n) = 2.02*(6.83/√42) = 2.1279

b. Lower level limit = 32.66 - 2.1279 = 30.5321; Upper level limit = 32.66+2.1279 = 34.7879. The interval estimate = (mean± margin of error) = (30.53, 34.79).

c. The mean prices for two in mid-range restaurants in Hong Kong are relatively less than those in Tokyo restaurants.
