Joanna, a machine learning engineer is studying what programming languages are the most effective to help systems learn from dat

a. Based on previous research, more than 50% of machine learning involves the use of Python, a programming language. She suspects this percent has increased in recent years. In the process of hypothesis testing, what set value will allow Joanna to make a conclusion about whether her sample proportion is "different enough" than the claimed population proportion?a. p-value
b. test statisticc. significance leveld. null hypothesis

Answer:

Option A

Step-by-step explanation:

The p-value will help Joanna in coming to a conclusion about her hypothesis. The p-value derived from the test statistics calculated gives an immediate accurate summary of inference information (using significance levels, confidence intervals etc) for the parameter of interest.

It is used as an alternative to rejection points; a smaller p value means there is stronger evidence leading to the rejection of the null hypothesis and vice versa.

You are running a concession stand at a basketball game. You are selling hotdogs and sodas. Each hotdog cost $1.50 and each soda
Lubov Fominskaja [6]

Answer:

35 hotdogs

Step-by-step explanation:

You are running a concession stand at a basketball game. You are selling hotdogs and sodas.

Let the number of hot dogs be represented by x

The number of soda be represented by y

You sold a total of 87 hotdogs and sodas combined

x + y = 87

x = 87 - y

Each hotdog cost $1.50 and each soda cost $0.50. At the end of the night you made a total of $78.50.

Hence we have the equation:

$1.50 × x + $0.50 × y = $78.50

1.50x + 0.50y = 78.50

Substitute 87 - y for x

1.50(87 - y) + 0.50y = 78.50

130.5 - 1.50y + 0.50y = 78.50

Collect like terms

- 1.50y + 0.50y = 78.50 - 130.50

-1.00y = -52

y = -52/-1

y = 52 sodas

How many hotdogs did you sell?

Using the equation:

x = 87 - y

x = 87 - 52

x = 35 hotdogs

Hence, you sold 35 hotdogs

Given that triangle x y z is congruent to triangle n m l, the measure of angle x equals 20 degrees, the measure of angle m equal
Delvig [45]

A triangle has a total angle of 180 degrees. Since we know that angle X = angle N = 20 degrees and angle Y = angle M = 75 degrees, therefore angle Z or angle L is equal to:

angle L = 180 – 20 – 75

<span>angle L =  85 degrees</span>

 

Therefore w is:

angle L = 5 (w – 2)

5 (w – 2) = 85

w – 2 = 17

<span>w = 19</span>
