Answer:
The correct option is;
Two-tailed test
Step-by-step explanation:
From the interpretation of the question statement, the trader wants to conduct a hypothesis test on the trader's claim that the proportion of stocks that offer dividends is different from 0.14
Given that the difference is hypothesized, then the null hypothesis, H₀ and the alternative hypothesis, H₁ should be written as follows;
H₀: Null hypothesis (no difference, or no change)
H₁: μ ≠ μ₀ which is hypothesizing difference which is known as a two-tailed test
The confidence level is then selected and the test statistic is calculated
Answer:
Profit = $265.04.
Selling price = $1329.05
Step-by-step explanation:
Paul brought a Computer at a cost price of $1064.
Now ,
The marked price of the computer is given as $1399.
Also,
He is giving a total discount of 5% on the marked price of the computer i.e., $1399.
So, The selling price of computer will become 95 percent of $ 1399 which equals $1329.05.
Thus Paul sold the computer at a profit of $1329.05 - $1064
= $265.04.
1. You can solve this problem and calculate the volume of the cooler, by following the proccedure below:
2. You have that the cooler measures <span>1 1/2 feet by 1 foot by 1 1/5 feet; then, you only have to multiply these values. Then, you have:
1 1/2 feet=1.5 feet
1 1/5 feet=1.2 feet
Volume of the cooler=(1.5 feet)(1 foot)(1.2 feet)
Volume of the cooler=1.8 feet</span>³
<span>
What is the volume of the cooler?
The answer is: T</span>he volume of the cooler is 1.8 feet<span>³</span><span>
</span>
Answer:
r = 144 units
Step-by-step explanation:
The given curve corresponds to a parametric function in which the Cartesian coordinates are written in terms of a parameter "t". In that sense, any change in x can also change in y owing to this direct relationship with "t". To find the length of the curve is useful the following expression;
In agreement with the given data from the exercise, the length of the curve is found in between two points, namely 0 < t < 16. In that case a=0 and b=16. The concept of the integral involves the sum of different areas at between the interval points, although this technique is powerful, it would be more convenient to use the integral notation written above.
Substituting the terms of the equation and the derivative of r´, as follows,
Doing the operations inside of the brackets the derivatives are:
1 )
2)
Entering these values of the integral is
It is possible to factorize the quadratic function and the integral can reduced as,
Thus, evaluate from 0 to 16
The value is
