Answer:

B

Step-by-step explanation:

When testing hypothesis to make a conclusion, you must find sufficient evident to reject the null hypothesis in favor of the alternative hypothesis. The null hypothesis must fail in order to accept the alternative. Failing to reject is not enough information. Since this is the case then options C and D are false statements and cannot be true. Both state that if you reject the null then the alternative is false or can't be supported. The opposite is true. Option A is also false since you cannot accept the null. You can only fail to reject it. If this is true then the alternative certainly cannot be accepted. Option B must be correct and the statement (thought not listed here) must be true.

A. This statement is false. A true statement​ is, "If you decide to accept the null​ hypothesis, then you can support the alternative​ hypothesis."

B. This statement is true.

C. This statement is false. A true statement​ is, "If you decide to reject the null​ hypothesis, then you​ can't support the alternative​ hypothesis."

D. This statement is false. A true statement​ is, "If you decide to reject the null​ hypothesis, then you can assume the alternative hypothesis is​ false."

If the equilibrium is such that only 12000 units are sold for $27, then the total earnings from the given scenario is $324,000. The supply equation would then be,
        supply: 324000 = 6p   ; p = 324000/6 = 54000
        demand: 324000 = 69p ; p = 324000/69 = 4695.65 ≈ 4696

When the outliers are removed, how does the mean change? dot plot with 1 on 50, 1 on 76, 1 on 78, 2 on 79, 1 on 80, 1 on 81, 2 o
sveticcg [70]
We can plot this data on MS Excel and determine the distribution of these data reflected on the graph. Among these numbers, 50 is the outlier since it is very far from the other numbers ranging from 76 to 83. We can perform interquartile range to determine or verify the outliers in the data set. In this respect, we can see that there is not much distribution seen. The average of all data sets is equal to 96.25. When the outlier (50) is removed, we expect the mean to become higher since a low number was ommitted including high numbers only. Outliers are obtained from special causations such as human errors.

Help now. a storage tank in the shape of a cuboid of base 2.5 m by 2 m can hold up to 7500 litres of water. Calculate the height
Minchanka [31]

Answer:

Height of the tank is 1.5m

Step-by-step explanation:

Given

Shape: Cuboid

Base Dimension = 2.5m by 2m

Volume = 7500 litres

Required

Determine the height of the tank

First, the area of the base has to be calculated;

Area = 2.5m * 2m

Area = 5.0m^2

Next is to calculate the height using volume formula;

Volume = Area * Height

Recall that Volume = 7500L [Convert to m³]

1 L = 0.001m^3

So;

7500L = 7500 * 0.001m^3

7500L = 7.5m^3

Hence;

Volume = 7.5m^3

Substitute 7.5m³ for Volume and 5.0m² for Area in the following formula

Volume = Area * Height

7.5m\³ = 5.0m\² * Height

Divide both sides by 5.0m²

\frac{7.5m\³}{5.0m\²} = \frac{5.0m\² * Height}{5.0m\²}

\frac{7.5m\³}{5.0m\²} = Height

1.5m = Height

Height = 1.5m

<em>Hence, the height of the tank is 1.5m</em>
