Based on past experience, a bank believes that 13% of the people who receive loans will not make payments on time. The bank has
g100num [7]

Answer:

The sample proportion mean and standard deviation are

\mu=p=0.13\\\\\sigma=\sqrt{\frac{p(1-p)}{N} }= \sqrt{\frac{0.13*0.87}{500} }=0.015

With reasonable assumptions about the sample, all the conditions are met.

The probability that over 16% of these clients will not make timely payments is P=0.023.

Step-by-step explanation:

We have a sample of 500 loans, of which a proportion of p=0.13 is expected to not be paid on time.

The sample proportion mean and standard deviation are

\mu=p=0.13\\\\\sigma=\sqrt{\frac{p(1-p)}{N} }= \sqrt{\frac{0.13*0.87}{500} }=0.015

The assumptions underlying this model are:

- The sample is randomly selected from the population.

- The sampling distribution of p-hat is approximately normal. There are at least 10 successes and 10 failures in the sample.

- Individual observations are independent of each other.

With reasonable assumptions about the sample, all the conditions are met.

What is the probability that over 16% of these clients will not make timely payments?

z=\frac{x-\mu}{\sigma} =\frac{0.16-0.13}{0.015}=\frac{0.03}{0.015}=2\\\\P(p>0.16)=P(z>2)=0.023

The probability that over 16% of these clients will not make timely payments is P=0.023.

Dad is getting food ready for my birthday party! Including me, there will be 10
Vaselesa [24]

There are 10 people and you want each of them to have 3 cupcakes. So multiply 10x3, which is 30. Then divide 30 by 8. You can't do that without a remainder though. So you round up to the nearest multiple of 8, which is 32. Then divide 32 by 8, which is 4. So tell dad to bake 4 batches, and the rest is for your dessert tomorrow.
