B. The mean of its sampling distribution is equal to the true value of the parameter being estimated
Answer:
so correct option is b. -27%
Explanation:
given data
job manufacturing industry = 63.1 thousand
annual rate = 1.7 thousand
time period = 10 year
solution
the total loss of jobs over the 10 years will be:
total loss = 1.7 × 10
total loss = 17 thousand jobs
so that the percent change will be
percent change = 
percent change = -27 %
so correct option is b. -27%
In order to break even, they would need to sell at least 5,000 units
Break even point is calculated by the formula:
Fixed costs÷(selling price -variable costs per unit)
i.e.
100,000 ÷ (60-40) = 5,000
Anything they sell above this number will start to produce profits for the company
What you’re talking about is Beta. Beta is the ratio of how much a stock changes relative to the market as a whole (NYSE, NASDAQ)
A Beta of 2.0 means it changes (up/down) twice as much as the general market (Dow, S & P, NAS), such as the twitchy, hyper reactive tech stocks ( FAANG’s and also boom-or-bust Big Oil). In other words, high Standard Deviations.
A Beta of 0.5 means it changes (up/down) half as much as the general market. Sleepy blue chips such as GE, AT&T or power utilities fall in that category. Low Standard Deviations
Most stocks by definition pretty much track the market (Beta 1.0) so there are a lot of those. Middling Standard Deviations
So…it is dictated by your risk tolerance.
