Answer:
The 80% confidence interval for the mean waste recycled per person per day for the population of New York is between 1.6 pounds and 4.2 pounds
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 11 - 1 = 10
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 10 degrees of freedom(y-axis) and a confidence level of . So we have T = 1.372
The margin of error is:
M = T*s = 1.372*0.98 = 1.3
In which s is the standard deviation of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 2.9 - 1.3 = 1.6 pounds
The upper end of the interval is the sample mean added to M. So it is 2.9 + 1.3 = 4.2 pounds
The 80% confidence interval for the mean waste recycled per person per day for the population of New York is between 1.6 pounds and 4.2 pounds
The value of variable x of the provided equation is equal to the fraction number 1/3.
<h3>What is the solution of equation?</h3>The solution of an equation is the value of the variable of the equation, for which the equation is satisfied.
To solve an equation for its variable, isolate the variable on one side of the equation using the mathematical operations.
The given expression is:
The equation has been solved for x. Cancel out the terms appears in both sides of the equation and has similar sign.
Take the variable one side of the equation and constants other side of it.
Thus, the value of variable x of the provided equation is equal to the fraction number 1/3.
