A study of an association between which ear is used for cell phone calls and whether the subject is​ left-handed or​ right-hande

d began with a survey​ e-mailed to 5000 people belonging to an otology online​ group, and 717 surveys were returned.​ (Otology relates to the ear and​ hearing.) What percentage of the 5000 surveys were​ returned? Does that response rate appear to be​ low? In​ general, what is a problem with a very low response​ rate?

Answer:

14.34%

Explanation:

To find the percentage of returned surveys over the total we divide and then multiply:

(717/5000)*100= 14.34%

The response rate appears to be low because it is less than 50% (which would be 2500 return surveys). Some statistical studies agree that 30 is the minimum number of observations a study must have, but this number does not ensure statistically significant results.  

The problem with a very low response rate is that survey´s answers does not significant represent the study population characteristics and so we cannot make inferences, correlations or regressions that are statistically significant. In this case, the conclusions that scientists make about association between the left-handed population and right-handed population with the use of cell phone calls could be wrong or not represent the population characteristics, which means answers are not trustful.

sergeinik [125]

Answer: Raises the levels of both productivity and income

Explanation:

In a closed Economy, there is no trade with the outside world.

That would mean that the GDP formula for their expenditure model will look like this,

Y = C + I + G

Where Y is (GDP)

C is consumption

I is investment and,

G is Government Spending

Investment is also known as Savings because it is the amount of Total income that is not spent after individuals CONSUME and the Government SPENDS,

I = Y - G - C.

When an economy SAVES MORE they are sacrificing consumption now for future consumption and saving more.

This means that there is more money to invest in Economic activities.

Since there is a higher Investment in Economic activities, we can expect higher CAPITAL STOCK which can drive Economic growth as it leads to greater productivity as well as greater income because the Economy is growing.

The Harrod-Domar model of economic growth speaks more on this.

The UCLA transportation economist Donald Shoup developed a formula to explain the rational maximum cruising time for parking. Ca
vekshin1

Answer:

The above elasticity suggests that by raising the curb parking price by 10% reduces the time drive are willing to cruise by only 7.1%. also the increase of curb pricing would make elasticity greater that shows that curb park pricing by 1% reduces the drivers that are willing to cruise by only 2.3 %

Explanation:

Solution

Given that:

Now, when we look at the papers designed by the economists for the various formulas of calculating elasticity related to six factors examples like, the price of off street parking, the price of fuel, the number of person or individuals in a car, the price of curb parking, time value, we would notice that the formula for calculating cruising time elasticity with that of  curb parking price is stated below:

E = - p/(m-p)

E = -5/12-5

E = -5/7

=-0.714

The above elasticity states that by raising the curb parking price by 10% reduces the time drive are willing to cruise by only 7.1%

Now,

The new elasticity  = -7/(10-7)

=-7/3

=-2.33 or 2.33%

It suggests that the increase of curb pricing would make elasticity greater that shows that curb park pricing by 1% reduces the drivers that are willing to cruise by only 2.3 %
