Answer:
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.
Answer:
Explanation:
Solution-
According to Senator Jones, the elasticity of taxable income is larger, which means that due to a certain percentage rise in taxes, the taxable income rises by a greater percentage. Also, according to Senator Smith, the elasticity of taxable income is small, which means that due to a certain percentage rise in taxes, the taxable income rises by a smaller percentage.
(I) Under Senator Jones assumptions, due to rise in taxes, the taxable income has risen considerably as compared to Senator Smith assumptions. Thus the estimates of additional revenue from the tax increase will be larger under Senator Jones assumptions, compared to Smith's assumptions.
(ii) Since under Senator Jones assumptions, elasticity of taxable income is large. So due to rise in taxes, there is a significant proportional rise in taxable income under Jone's assumptions compared to Senator Smith assumptions. Thus the costs of the tax increase is borne more under Senator Jones assumptions , compared to Smith's assumptions.

Designer worksheet is the one such document which states the work or the potential in the designer or the person. It is that document which contains or comprise of the portfolio of the designer, having or shown the previous work which is done by the designer or the person in his or her last company and the few or some of the sample designs which provide an idea to other person regarding the potential or taste of the designer.
Answer:
The answer is option C) Sampling Bias
Explanation:
A researcher who is conducting observations to test her own hypothesis may see or pay more attention to behavior that tends to support that hypothesis, so she must guard against observer bias
Observer bias is the tendency to allow how we feel or what we expect influence what we see.
As a researcher conducting observations to test her own hypothesis, it is possible that she may feel or think a certain way that will influence her observation.
knowledge of observation bias and how to guard against it will help her eliminate such error.
