The conclusion of the research is that we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.

We are given;

Population Mean; μ = 426

Sample mean; x' = 433

Sample size; n = 13

Standard deviation; s = 29

significance level; α = 0.05

Let us define the hypotheses;

Null Hypothesis; H₀: μ = 426 g

Alternative Hypothesis; H_a: μ < 426 g

Formula for the z-score here is;

z = (x' - μ)/(s/√n)

z = (433 - 426)/(29/√13)

z = 0.87

From online p-value from z-score calculator, we have;

p-value =  0.1922

This p-value is greater than the significance value and as such we reject the null hypothesis and we conclude that the bag filling machine does not work correctly at the 426 gram setting.

The joint probability mass function based on the given experiment is as seen in the attached file.

The whole sample space consists of 36 elements, i.e.,

Ω = {ω_ij = (i, j) : i, j = 1, ....6}

Now, with each of these 36 elements associate values of two random variables, X₁ and X₂, such that;

X₁ ≡ sum of the outcomes on the two dice.

X₂ ≡ |difference of the outcomes on the two dice|

That is;

X(ω_ij) = X₁(ω_ij) + X₂(ω_ij) = (i + j, |i - j|) i, j = 1, 2, ...., 6

Then, the bivariate rv X = (X₁, X₂) has the following joint probability mass

The mean of the temperature based on the information given is -3.2.

The difference in the temperature based on the information will be:

98.4 - 99.0 = -0.6

98.7 - 99.3 = -0.6

97.5 - 97.9 = -0.4

97.3 - 96.9 = 0.4

97.1 - 97.5 = -0.4

Total = -1.6

The mean will be:

The standard error is 1.5.

The range of 95% confidence interval is 160 mg/dL and 220 mg/dL

The standard error of the distribution is calculated as follows:

where N is the number of participants = 100

From the empirical rule of a normal or symmetrical distribution;

Therefore,  175 mg/dl and 205 mg/dl lie one standard deviation from the mean.

One standard deviation = 175 - 190 or 205 - 190 = ±15

Standard deviation = 15

a. Solving for the standard error using the equation above;

Standard error = 15/√100

Standard error = 1.5

b. The range of 95% confidence interval is two standard deviations away from the mean.

Range of values two standard deviations from the mean = 190 - (2*15) and 190 + (2 * 15)

Range of values two standard deviations from the mean = 160 mg/dL and 220 mg/dL

Therefore, the range of 95% confidence interval is 160 mg/dL and 220 mg/dL

In conclusion, the standard error is calculated from the standard deviation and the sample size.

Explanation:

They are a tool for others to judge you and your mistake

Answer:

C. They are a learning tool for judging yourself

Explanation:

Examinations and assessments aren't meant to point out your failures or show what you don't know because not everyone makes mistakes on tests and exams, and if they do, those mistakes could have very well been careless. They also aren't a tool for others to judge you and your mistakes because no one is perfect, and people should judge you based on your overall personality and actions, not your test scores.

C is correct because tests and exams are a learning tool... If you do miss anything, you can refer back and study them to prepare for the next test or review what you missed. They allow you to judge yourself by letting you look at where you are now and compare it to where you should be in a healthy way.

The p-value (0.0001) is less than α = 0.05. Based on this, we should reject the null hypothesis.

A null hypothesis (H₀) can be defined the opposite of an alternate hypothesis (H₁) and it asserts that two (2) possibilities are the same.

The test statistic can be calculated by using this formula:

[tex]t=\frac{x\;-\;u}{\frac{\delta}{\sqrt{n} } }[/tex]

Where:

For this clinical trial (study), we should use a t-test and the null and alternative hypotheses would be given by:

H₀: p = 0.028

H₁: p > 0.028

For the sample proportion, we have:

Sample proportion, P = 28/888

Sample proportion, P = 0.032.

Next, we would calculate the t-test as follows:

[tex]t=\frac{0.032\;-\;0.028}{\frac{0.02 \times 0.028}{888 } }\\\\t=\frac{0.004}{\sqrt{\frac{0.00056}{888 } }}[/tex]

t = 0.004/0.00079

t-test, t = 5.06.

For the p-value, we have:

P-value = P(t > 5.06)

P-value = 1 - P(t < 5.06)

P-value = 1 - 0.9999

P-value = 0.0001.

Therefore, the p-value (0.0001) is less than α = 0.05. Based on this, we should reject the null hypothesis.

Answer:

Possible values:

0 and 12

Explanation:

To solve the system of equations, let's set y = x^2 - 4x + 3 and y = x - 1 equal to each other to first solve for x.

x^2 - 4x + 3 = x - 1 (add one to both sides)

x^2 - 4x + 4 = x (subtract x from both sides)

x^2 - 5x + 4 = 0

Next, we simply factor the expression. -1 and -4 add up to -5 and multiply to 4, so the factored expression looks like this:

(x - 1)(x - 4) = 0

x = 1 and x = 4 are both solutions to the factored equation. Now, let's plug the values back in to both equations.

(1)^2 - 4(1) + 3 = 0

(4)^2 - 4(4) + 3 = 3

(1) - 1 = 0

(4) - 1 = 3

When 1 is plugged into either equation, 0 is the value of y. For 4, 3 is the value of y. The possible values of product of x and y are below:

0 * 1 = 0

4 * 3 = 12
