A business analyst is investigating whether the mean amount of purchases made by customers at an online department store is greater than $100. The analyst obtained a random sample of 56 orders and calculated a sample mean of $102.30 and a sample standard deviation of $5.30.
Which of the following is an appropriate test for the investigation?

Answers

Answer:

B

Step-by-step explanation:

I don't know

An appropriate test for the investigation is, One sample t-test for sample mean. So option B is correct

What is a random sample ?

The process of selecting a sample of data from a population in order to draw conclusions about the population is known as random sampling. Additionally known as probability sampling. Non-probability sampling, often known as non-random sampling, is this sample's opposite. Simple random sampling, stratified sampling, cluster sampling, and multistage sampling are the main forms of this sampling. Convenience samples are often referred to as non-arbitrary samples in sampling methodologies.

Given that,

Population mean = $100

Sample = n = 56

Sample mean =  $102.30

sample standard deviation = $5.30

So, all the data mean, standard deviation is given

therefore, t-test used and one type of sample used as well

Hence, It is one-sample t-test for sample mean

Find the unit rate.Round to the nearest hundredth,if necessary. 2.99 for 16 lb I REALLY NEED HELP !!!

Answers

9514 1404 393

Answer:

  0.19/lb

Step-by-step explanation:

When computing cost per quantity, the cost is divided by the quantity.

  2.99/(16 lb) = 0.186875/lb ≈ 0.19/lb

Answer:

heyy it's me again lol but  The unit rate is $0.19/lb.

Step-by-step explanation:

Divide the total by the number of pounds to get the price per pound, or the unit rate.

$2.99 ÷ 16 lb = 0.186875

Since 0.186875 isn't an accurate US dollar amount, round  to nearest hundredth, 0.19.

so you answer is $0.19/Ib

Step-by-step explanation:

Sophia invested $79,000 in an account paying an interest rate of 6.8% compounded
continuously. Assuming no deposits or withdrawals are made, how long would it
take, to the nearest year, for the value of the account to reach $152,800?

Answers

Answer:

10

Step-by-step explanation:

The value of the account will reach $152,800 in 10 years.

What is Compound Interest?

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

Interest compounded continuously means there is no limit for the process of compound of interest. It is compounding infinite times.

The formula for calculating the final amount when the interest is compounded continuously is,

A = P e^(r t)

Here, A is the final amount, P is the initial or principal amount, r is the rate of interest and t is the number of years.

Given that,

A = $152,800

P = $79,000

r = 6.8% = 6.8/100 = 0.068

We have to calculate t.

152,800 = 79,000 e^(0.068 t)

152,800 / 79000 = e^(0.068 t)

1.934 = e^(0.068 t)

Taking logarithms on both sides,

㏑ 1.934 = ㏑ e^(0.068 t)

We have ㏑(a)ⁿ = n ㏑(a)

0.65968 = 0.068t ㏑ e

0.65968 = 0.068 t × 1

t = 9.7 ≈ 10 years

Hence the amount is compounded to $152,800 in 10 years.
