Answer:
a) The 95% confidence interval for the mean waste recycled per person per day for the population of Maine is between 1.19 and 1.61 pounds.
b) 
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used 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 = 7 - 1 = 6
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 6 degrees of freedom(y-axis) and a confidence level of
. So we have T = 2.4469, and the answer to question b is 
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 1.4 - 0.21 = 1.19 pounds.
The upper end of the interval is the sample mean added to M. So it is 1.4 + 0.21 = 1.61 pounds.
The 95% confidence interval for the mean waste recycled per person per day for the population of Maine is between 1.19 and 1.61 pounds.
Bro i need major help right now too but um idek what to do but good luck
Answer:
2p-1
Step-by-step explanation:
-4p-(1-6p)
when there is "-" in front of an expression, change the sign of each term of the expression.
-4p -1 + 6p
-4p + 6p =2p
2p -1
-77 and 7/20 is the answer simplified and without it being simplified you get -77 and 35/100
Frist we need to find the mean of both so
1.55
2.67
then we make a number graph and see how mant place does it take to get to them from 0 67and55/by them selfs = 1.2(rounded)
1.2 is you answer
