Ecologists wanted to estimate the mean biomass (amount of vegetation) of a certain forested region. The ecologists divided the region into plots measuring 1 square meter each, and they selected a random sample of 9 plots. The mean biomass of the 9 plots was 4.3 kilograms per square meter and the standard deviation was 1.5 kg/m^2. Assuming all conditions for inference are met, which of the following is a 95% confidence interval for the population mean biomass, in kg/m^2?

a. 4.3 ± 1.96 (√ 1.5/3)
b. 4.3 ± 1.96 (1.5/3)
c. 4.3 ± 2.306 (√ 1.5/9)
d. 4.3 ± 2.306 (1.5/9)
e. 4.3 ± 2.306 (1.5/3)

its a little blurry tbh

step-by-step explanation:

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
