Answer:
d. Independent-samples t-test
Step-by-step explanation:
The independent samples t-test can be described as a test under which two groups are compared on the mean value of a continuous normally distributed variable.
The independent samples t-test model is based on the assumption that the mean score of the dependent variable is different because the of the impact of the independent variable that differentiates the two groups.
The independent-samples t-test is also known as a parametric test in which the means of two independent groups are compared with the aim of ascertaining if there is statistical evidence that the associated population means are significantly different.
In this question, there are two independent groups which we intend to compare in order to investigate the effect of antidepressants. The first group is the group of people given antidepressant, while the second is another group of people that is given a placebo. This is a perfect example of independent-samples t-test.
Therefore, the correct option is d. Independent-samples t-test. That is, the type of parametric test that should be run in order to investigate the effect of antidepressants by giving one group of people an antidepressant and another group of people a placebo.

The number of years a Mars rover is expected to function on the surface of Mars is exponentially distributed with parameter λ = 0.25. If the company Budget Mars Explorer Inc. successfully lands a Mars rover on the planet Mars, what is the probability that it will be working for an additional 10 years after it last sent a communication to mission control?
Answer:
the probability that it will be working for an additional 10 years after it last sent a communication to mission control is 0.0821
Step-by-step explanation:
Given that;
years a Mars rover is expected to function on the surface of Mars λ = 0.25
probability that it will be working for an additional 10 years after it last sent a communication to mission control?
Now x is number of years a Mars rover function
f(x) = 0.25e^-0.25x , 0 < n < ∞
so
P( X>10 ) = ₁₀∫^∞ 0.25e^(-0.25n) dn
= e^(-0.25 × 10)
= e^(-2.5})
= 0.0821
therefore the probability that it will be working for an additional 10 years after it last sent a communication to mission control is 0.0821

A company manufactures batteries in batches of 26 and there is a 3% rate of defects. Find the standard deviation for the number of defects per batch.
Answer:
The standard deviation for the number of defects per batch is 0.87.
Step-by-step explanation:
Let X denote the number of defective batteries per batch.
A company manufactures batteries in batches of n = 26.
It is provided that the rate of defects is, p = 0.03.
Each battery is defective independently of the others.
The random variable X follows a binomial distribution.
The standard deviation of a binomial distribution is:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
Compute the standard deviation for the number of defects per batch as follows:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
[tex]=\sqrt{26\times 0.03\times (1-0.03)}\\\\=0.86982757\\\\\approx 0.87[/tex]
Thus, the standard deviation for the number of defects per batch is 0.87.

Answer:
B.(-3,0)
Step-by-step explanation:
i just finished the test
(-3,0) point is a solution to the inequality shown in this graph.
What is the definition of inequality?Inequality is a sort of equation in which the equal sign is missing. As we will see, inequality is defined as a statement regarding the relative magnitude of two claims.
There are two solutions os inequality are;
(0,4)
(-3,0)
But only one solution is given in the graph as;
(-3,0)
Hence, the (-3,0) is the point that is a solution to the inequality shown in this graph. Option B is correct.

How will increasing the level of confidence without changing the sample size affect the width of a confidence interval for a population mean?
Answer:
The width of the confidence interval is going to be wider
Step-by-step explanation:
When we Increase the level of confidence without changing the sample size the width of the confidence interval is going to be affected in the following way;
The margin of error (M.E) is going to be larger or be increased. This increase is due to the fact that the critical value is going to increase. Then the increased margin of error would cause the width of the confidence interval to become wider.
