The probability that randomly selected person aged 35 years or older is male and jogs is 0.03922.
It is usual to randomly select a person aged 35 years and older who is male and jogs since it's less than 0.05.
How to calculate the probability?From the information, there is a 18.5% probability that a randomly selected person aged 35 years or older is a jogger.
Also, there is a 21.2% probability that a randomly selected person asked 35 years or older is male, given that he or she jogs.
Therefore, the probability will be the multiplication of both probabilities given. This will be:
= 21.2% × 18.5%
= 0.03922

In a study of the accuracy of fast food drive-through orders, one restaurant had 40 orders that were not accurate among 318 orders observed. Use a 0.01 significance level to test the
claim that the rate of inaccurate orders is equal to 10%. Does the accuracy rate appear to be acceptable?
A normal distribution with a mean of zero and a standard deviation of one is known as the standard normal distribution. yes it is acceptable
Explain about the Standard normal distribution?One type of the normal distribution is the standard normal distribution. It happens when a typical random variable's mean and standard deviation are both one. In other terms, the term "standard normal distribution" refers to a normal distribution with a mean of 0 and a standard deviation of 1.
The mean, median, and mode of a normal distribution are all equal and it is symmetric, unimodal, and asymptotic. Perfect symmetry surrounds the center of a normal distribution. To put it another way, the left and right halves of the center are mirrored.
The standard normal distribution is centered at zero, and the standard deviation indicates how much a specific measurement deviates from the mean.
n = 381
Number of orders that were not exact as a percentage = 40/318 =0.125
= P - P/√p(1 - p)/n
= 0.125 - 0.10/√0.10(0.90)/381
= 0.025/√0.09/381
=0.025/0.048
=0.52

A student proposes the following hypothesis: There is a significant association between level of education (matric, undergraduate/diploma, honours, masters, PhD) and employment (Yes/No). What test should they use to answer the hypothesis and why?
The test that should be used to answer or test the above Hypothesis is The chi-square test of independence. The reason this test ought to be used is that the Chi-Square Test of Independence examines whether or not categorical variables are connected (i.e., whether the variables are independent or related). It is a nonparametric examination.
What is a hypothesis?It is to be noted that a hypothesis is an explanation provided for a phenomenon. The scientific method demands that a hypothesis be testable in order for it to be considered a scientific hypothesis. Scientists often establish scientific hypotheses on past data that cannot be adequately explained by existing scientific ideas.
A hypothesis allows researchers to not only find but also forecast a link between variables based on theoretical principles and/or actual data. Creating a hypothesis necessitates a thorough comprehension of the study issue as well as a thorough assessment of prior literature.

Billy purchased a certificate of deposit 7 years ago for $1,000. If the certificate of deposit is due
today in the amount of $2,000, what is the average annual compound rate of return, assuming
monthly compounding, that Billy realized on his investment?
The average periodic emulsion rate of return is 9.94.
What's composite interest?
The interest on the original star as well as any posterior interest gained on the investment are both considered when calculating emulsion interest. The quantum of interest generated on the original investment increases with longer compounding ages.
What do you understand by the Investment?
The term" investment" refers to a purchase made with the stopgap of earning plutocrat or adding one's wealth. Appreciation describes the process of an asset's value rising through time. When someone invests in a product, they do so with the intention of using it to induce plutocrat in the future rather than for immediate consumption.
Given,
Star P = $,000
Maturity quantum A = $,000
Yearly Time ages = 7 times x 12 months = 84 months
Yearly Rate of Interest r = ?
Average Periodic emulsion rate of interest = 12r
We know,
[tex]A=P\times(1+r)^n[/tex]
[tex]2000=1000\times(1+r)^{84}\\2 = (1+r)^{84}[/tex]
1 + r = 1.00828
r = 0.00828
thus Periodic emulsion rate = 12r = 12 x0.00828 = 0.09936 or9.94

If the resultant of two equal forces is 2 times the single force, find the angle between them.
The angle subtended between the forces is 180°.
What is the resultant force?The resultant force is said to be the force that has the same effect in magnitude and direction as two or more forces acting together. We know that force is a vector quantity.
Now we are told in the question that the resultant of two equal forces is two times the single force. Let the force shown as A and let the resultant be Aa.
Now;
Aa = 2Asin(m/2)
Then
Aa = 2A
2Asin(m/2) = 2A
