Suppose your dog posit $250 in a new savings account paying a Yield of 3% interest if the count is left alone how much money wil

Fed [463]

Answer:

The amount after a time period of 5 years is $287.5.

Step-by-step explanation:

Principal Amount deposited = $250

Time = 5 Years

Rate of interest = 3%

Now, SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

⇒ $SI = \frac{250 \times 3 \times 5}{100} = 37.5$

or, the interest amount after 5 years = $37.5

Now, AMOUNT = PRINCIPAL + INTEREST

= $250 + $37.5 = $287.5

Hence the amount after a time period of 5 years is $287.5.

A marketing consultant observed 40 consecutive shoppers to estimate the average money spent by shoppers in a supermarket store.

KonstantinChe [14]

Answer:

0.998 is the probability that the average money spent by a sample of 40 shoppers is within $10 of the actual population mean.

Step-by-step explanation:

We are given the following information in the question:

Standard Deviation, σ = $21.51

We are given that the distribution of average money spend is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

We have to find:

P( average money spent is within $10 of the actual population mean.)

$= P( z \leq \displaystyle\frac{10\times \sqrt{40}}{21.51}}) = P(z \leq 2.94)$

Calculation the value from standard normal z table, we have,

$P(z \leq 2.94) = 0.998$
