What price do farmers get for the peach crops? in the third week of June, a random sample of 40 farming regions gave a sample me
prohojiy [21]
Given:
Sample size, n = 40
Sample mean, xb = $6.88
Population std. deviation, σ = $1.92 (known)
Confidence interval = 90%

Assume normal distribution for the population.
The confidence interval is
(xb + 1.645*(σ/√n), xb - 1.645*(σ/√n)
= (6.88 + (1.645*1.92)/√40, 6.88 - (1.645*1.92)/√40)
= (7.38, 6.38)

Answer: The 90% confidence interval is (7.38, 6.38)

3400 dollars is placed in an account with an annual interest rate of 8. 25%. How much will be in the account after 25 years, to
OLEGan [10]

The final amount in the account after 25 years is $24670.42.

<h3>How do you calculate the final Amount after 25 Years?</h3>

Given that 3400 dollars are placed in an account with an annual interest rate of 8.25% for 25 years.

The final amount in the account is calculated by the formula given below.

A = P ( 1 + \dfrac {R}{100})^T

Where A is the final amount, P is the initial principal balance, R is the interest rate, T is the time period.

The final amount is given below.

A = 3400 ( 1 + \dfrac {8.25}{100})^{25}

A = 3400 (7.256005874)

A = 24670.41997= 24570.42

Hence we can conclude that the final amount in the account after 25 years is $24670.42.
