All the fourth-graders in a certain elementary school took a standardized test. A total of 82% of the students were found to be proficient in reading, 74% were found to be proficient in mathematics, and 65% were found to be proficient in both reading and mathematics.A student is chosen at random. What is the probability that the student is proficient in neither reading nor mathematics

Answers

Answer:

0.09 = 9% probability that the student is proficient in neither reading nor mathematics

Step-by-step explanation:

We solve this question treating the events as Venn probabilities.

I am going to say that:

Event A: A student is proficient in reading.

Event B: A student is proficient in mathematics.

A total of 82% of the students were found to be proficient in reading

This means that [tex]P(A) = 0.82[/tex]

74% were found to be proficient in mathematics

This means that [tex]P(B) = 0.74[/tex]

65% were found to be proficient in both reading and mathematics.

This means that [tex]P(A \cap B) = 0.65[/tex]

What is the probability that the student is proficient in neither reading nor mathematics?

This is:

[tex]P = 1 - P(A \cup B)[/tex]

In which

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

With the values that we have:

[tex]P(A \cup B) = 0.82 + 0.74 - 0.65 = 0.91[/tex]

Then

[tex]P = 1 - P(A \cup B) = 1 - 0.91 = 0.09[/tex]

0.09 = 9% probability that the student is proficient in neither reading nor mathematics

A music therapist was interested in investigating whether listening to music or composing music had an influence on both anxiety levels and oxygen saturation in children who were hospitalized for asthma-related illnesses. Thirty-two children spent 20 minutes listening to classical waltzes played on a piano. On a different day, they spent 20 minutes composing their own short pieces of music using a software program.
When listening to music: For the physiological measure, the critical value for t was larger than the test statistic for the observed data. For the anxiety measure, the critical value for t was smaller than the test statistic for the observed data.
When composing music: For the physiological measure, the critical value for t was larger than the test statistic for the observed data. For the anxiety measure, the critical value for t was larger than the test statistic for the observed data.
When writing the results of the music therapist's study, which of these statements reflects the correct conclusions that should be drawn from the results and then included as part of the interpretation paragraph?Question 8 options:
a) Music therapists should make pediatric asthma patients compose music in order to increase their oxygen saturation.
b) Music therapists should make pediatric asthma patients listen to music in order to reduce their anxiety.
c) Pediatric asthma patients should listen to music in order to increase their oxygen saturation.
d) Additional information is needed to draw a proper conclusion.

Answers

Answer:

The correct conclusion is;

d) Additional information is needed to draw a proper conclussion

Step-by-step explanation:

The given parameters are;

When listening to music;

Physiological measure Critical t > Test statistic Accept H₀

Anxiety measure Critical t < Test statistic Reject H₀

When composing music;

Physiological measure Critical t > Test statistic Accept H₀

Anxiety measure Critical t > Test statistic Accept H₀

When the test statistic is larger the critical 't'

Therefore, the test suggest that there is no difference between physiological and anxiety influence of composing music on pediatric asthma patients

There is sufficient statistical evidence to suggest that listening to music has an influence on the anxiety of pediatric asthma patients however, the nature of the influence is not specified and more information is needed to draw a proper conclusion

Expected rate of return and risk - B.J. Gautney enterprises is evaluating a security. One year treasury bills are currently paying 4.3 %. Calculate the investment's expected return and its standard deviation. Should Gautney invest in this security?
Probability/ return: 0.20/ -4%; 0.50/ 4%; 0.10/ 7%; 0.20/ 8%.
The investment's expected return is _% (round the two decimal places)
The investment's standard deviation is % (round the two decimal places)
Should Gautney invest in this security? (select the best choice below)
a) yes. B.J. Gautney Enterprices should invest in this investment because the return is lower than treasury bill and the level of risk higher than the treasury bill.
B) no. B.J. Gautney Enterprises should not invest in this investment because the return is lower than the treasury bill and the level of risk higher than the treasury bill.

Step-by-step explanation:

[tex]\text{Investment's Expected Return} = (0.20 \times -0.04) + (0.50 \times 0.04) + (0.10 \times 0.07) + (0.20 \times 0.08) \\ \\ = (-0.008)+(0.02)+(0.007) + (0.016) \\ \\ \text{= 0.035}\\ \\ = 3.50\%}[/tex]

[tex]Var (r) = [(-0.04- 0.035)^2 * 0.2] + [(0.04 - 0.035)^2 * 0.5] + [(0.07 - 0.035)^2 * -0.10] + [(0.08 - 0.035)^2 * 0.20] \\ \\ = (-5*10^{-6} )+(1.25*10^{-5})+(-1.225*10^{-4}) + (4.05 \times 10^{-4}) \\ \\= 0.001665[/tex]
