Naomi weighed 50 patients for a medical study using a scale that measures to the nearest whole pound. She then calculated the me
1 answer:
99.7 percentage of the data lies between 140 and 212 pounds when the distribution of the standard deviation is normal.
<h3>What is standard deviation?</h3>Any given quantity, which is used to express that how many observations differ from others in the total observations of a data, is referred to as standard deviation. It is represented by σ.
To calculate the percentage of data lying between the given values, we will use the formula of empirical method and the given information to compute as under,
Solving further,
Hence, the significance upon the standard deviation of data weighted by Naomi is as aforementioned.

Answer:
The profit maximizing output level declines by 2.5 units and the price rises by $100.
Explanation:
In a monopoly market the inverse demand curve is given as,
P = 1,200 - 40Q
The marginal cost of production of the last unit is $200.
The total revenue is
=
=
The marginal revenue of the last unit is
=
= 1,200 - 80Q
At equilibrium the marginal revenue is equal to marginal price,
MR = MC
1,200 - 80Q = 200
80Q = 1,000
Q = 12.5
Putting the value of Q in the inverse demand function,
P =
P = $700
Now, if the marginal cost rises to $400,
At equilibrium the marginal revenue is equal to marginal price,
MR = MC
1,200 - 80Q = 400
80Q = 800
Q = 10
Putting the value of Q in the inverse demand function,
P =
P = $800
Answer:
a. increase price in the short run but not in the long run.
Explanation:
A perfectly competitive market is one in which firms in an economy produce similar goods, and use resources that are limited in quantity.
An increase in demand will result in a corresponding increase in price, and results in firms making high profits. In the diagram below it results in a shift of demand from D1 to D2.
In the long run as firms have low barrier to entry more firms enter the market and supply shifts from S1 to S2. There is reduction in prices and profits start to fall. This is illustrated in the second diagram.
