Answer:

The correct choice is (C).

Step-by-step explanation:

The p-value is defined as the probability, under the null hypothesis (H₀), of obtaining a result that is equal to or greater than the actual observed result in a statistical hypothesis test.

A small p-value (usually ≤ 0.05) indicates strong evidence against the null hypothesis (H₀), resulting in its rejection.

A larger p-value (> 0.05) indicates weak evidence against H₀, which leads to failure in rejecting the null hypothesis.

A nutritionist has concerns that the actual average calorie content of the french fries served at a fast-food restaurant exceeds 120 calories.

The testable hypothesis can be stated as:

H₀: The actual average calorie count in the french fries is 120 calories, meaning μ = 120.

Hₐ: The average calorie count in the french fries exceeds 120 calories, meaning μ > 120.

The statistical test is as follows:

The average calorie count among the 35 sampled small orders of fries is:

Consequently, the p-value is:

p-value = 0.00093

<pthis>p-value represents the probability of achieving a sample mean of 155.6 calories or higher when the population mean is 120 calories.

In summary,

The interpretation of the p-value can also include the probability of observing a mean of 84.4 calories or less when the population mean is established at 120 calories.

*Given the symmetry of the normal distribution, P(Z < -z) = P(Z > z).

Thus,

Therefore, the appropriate choice is (C).

Answer: We discover two outcomes:

1000 - 998 = 2

1001 - 999 = 2

Step-by-step explanation:

The problem can be stated as:

****-*** = 2

Where each asterisk symbolizes a distinct digit; here with a 4-digit number subtracting a 3-digit number to yield a difference of 2.

This can be represented as 99*, where we can increase any digit from 1 to 9 and we will achieve a 4-digit result:

So we rewrite it this way:

1000 - 998 = 2

When we add one to each side, the difference remains preserved, maintaining equal digit counts:[

1000 - 998 + 1 - 1 = 2

(1000 + 1) - (998 + 1) = 2

Thus, 1001 - 999 = 2

A simple case would also yield further solutions where digits can be zeros, for instance:

0004 - 0002 = 2

However, this trivial solution may be disregarded. This leads us to conclude that we have two unique solutions.

<span>To determine the quantity of tropical fish a tank can accommodate, calculate the volume by multiplying length, height, and width to obtain cubic centimeters of the aquarium, then divide that result by 10,000. Hence, 60*50*30 results in 90,000 cubic centimeters. Dividing 90,000 by 10,000 yields 9. Therefore, a tank with these measurements can hold 9 tropical fish.</span>

Answer:

The first equation is y = 1.5x - 6

The second equation is y = -4x + 6.1

The solution is (2.2, -2.7)

Step-by-step explanation:

There can be various responses to this query. Usually, the next number following 16 has digits that add up to 8.

Explanation:

First number 31 – The digits add up to 3 + 1 = 4  

Second number 1031 – The sum of the digits is 1 + 0 + 3 + 1 = 5

Third number 402 – The digits sum to 4 + 0 + 2 = 6

Fourth number 16 – Adding the digits gives 1 + 6 = 7

Thus, the missing number could either be the single digit 8 or any of these two-digit options: 17, 26, 35, 44, 53, 62, 71, or 80. It may also include larger numbers consisting of the digits from the mentioned two-digit figures combined with 0, like 260 or 7001.
