In a certain region, 94 percent of the people have a certain characteristic in their blood. Suppose a group of 45 people from th
Damm [24]

The best interpretation of the mean is;

Option A; For all groups of 45 people, the average number of people without the characteristic is 2.7

<h3>Interpretation of Mean</h3>

We are given;

Percentage of people with a certain characteristic in their blood = 94%

Number of people selected = 45

Number of people without the characteristic in their blood = B

Now, we are told that B  follows a binomial distribution with a mean of 2.7 people.

Now, in statistics, mean is defined as the average of a set of data.

Thus, this mean refers to the average number of people that don't have the characteristic in their blood from the group of 45 people.

The missing options are;

A) For all groups of 45 people, the average number of people without the characteristic is 2.7.

B) Every group of 45 people will have 2.7 people with the characteristic.

C) Every group of 45 people will have 2.7 people without the characteristic.

D) On average, 2.7 people are selected until finding someone with the characteristic

E) On average, 2.7 people are selected until finding someone without the characteristic

15. For a random sample of n = 64, find the probability of a sample mean being
mart [117]

Answer:

0.9726

Explanation:

The computation of the probability of a sample mean is shown below:

P(\bar x < 24.3)

To find the probability first we have to determine the z score which is

z = \frac{\bar x - \mu_{\bar x}}{\sigma_{\bar x}} \\\\ = \frac{\bar x - \mu }{\frac{\sigma}{\sqrt{n} } } \\\\ = \frac{24.3 - 24}{\frac{1.25}{\sqrt{64} } }

= 1.92

Now probability is

P(\bar x < 24.3) \\\\= P(z < 1.92)

= 0.9726

Hence, the probability of the sample mean is 0.9726

We simply applied the above formulas to determined the probability of a sample mean and the same is to be considered

What can you say about the series an in each of the following cases?
Likurg_2 [28]

The exercise is related to the Ratio Test for Convergence. The rules for this kind of test are given below.

<h3>What are the rules for Ratio Test for Convergence?</h3>

The rules are:

  • If the limit is less than 1 when conducting the ratio test, your series is definitely convergent.
  • The test is inconclusive if the limit is equal to 1.
  • The series is divergent if the limit is greater than 1.

Using this knowledge, we are able to state that

  • A is not conclusive.
  • C's convergence is absolute.
  • There is divergence with D and E.
  • B and F appear to be employing the nth-term test. The nth-term involves determining the sequence's limit as it approaches infinity.

The nth-term test determines whether a series is divergent if the limit is bigger than 0, thus, both B and F are divergent series.

Please see the attached for the full question and the link below for more about Ratio Test for Convergence:

Which equation is an example of the commutative property of multiplication? (4 2i) = (2i 4) (4 2i)(3 – 5i) = (3 – 5i)(4 2i) (4 2
kozerog [31]

Option B is correct. (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication

Given two values A and B, according to the commutative property of multiplication;

  • AB = BA

This shows that the product of A and B stays the same no matter the arrangement.

From the given option, we can see that (4 + 2i)(3 – 5i) = (3 – 5i)(4 + 2i) satisfies the commutative property of multiplication where we can say;

A = 4 + 2i and B = 3 - 5i
