Answer:
We can first order the data from smallest value to largest value:
461
549
745
1500
1800
2000
3750
4795
68000
a) The mean is 9289, and the median is 1800
b) The data does have an outlier, which is 68000, because it is more that three standards deviations away from the mean, excluding this value, our new mean is 1950 and our new median is 1650. We can see that the greatest change in value was for the mean.
c) the median is more appropriate because the median is less sensitive to outliers. The mean can be easily swayed by outliers in either way, and this can give an erroneous impression of the data.
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:
This question requires us to calculate cash flows from operations and net income. Each of them is calculated as follow.
Cash flows from operations
Cash flow from operation comprises of cash generated or spend on core business related purchase and sale. It will be calculated as follow.
Cash from operations = 25,000 - 100,000 =($ 75,000).
Net income
Net income will be calculated using simple cashflow equation given below.
Closing cash balance = opening cashflow + net income + depreciation + cash flow from operations + cash flow investment + cash flow finance
25,000 = 55,000 + net income + 10,000 - 75,000 - 250,000 + 170,000
Net income = 115,000
True, because the more variables the better
An economy is operating at full employment, and then workers in the bread industry are laid off. this change is portrayed in the movement from C to F.
The economy in points A, B, C, and D is at full employment. Some employees make bread, while others make wine. Points F and G depict scenarios where the unemployment rate varies depending on the state of the economy. Point E illustrates a growing economy that is performing above its maximum level of employment. When the unemployment rate is between 4% and 5%, an economy is considered to be in full employment; nonetheless, frictional unemployment is always present.
Given that the economy was at full employment when the question was asked, but that unemployment then rose, the starting point must be A, B, C, or D, and the final position must be F or G. Only option D, from points C through F, makes sense.
