Step-by-step explanation:
1. To find the slope given two points, use the following formula:
2. would be the second y-value (in the second ordered pair), 2, and
would be the first y-value (in the first ordered pair), also 2.
3. Same for the x-values. is -2 and
is 4
4. Now plug in the values.
5. This equals which simplifies to 0
Answer: (3.3, 3.5)
Step-by-step explanation:
The formula to calculate the confidence interval is given by :-
, where = sample mean.
z* = critical value.
= Population standard deviation.
n= Sample size.
As per given , we have
n= 217
By using z-table , the critical value for 95% confidence level : z* = 1.96
Now, the 95% confidence interval for the mean consumption of meat among males over age 50 will be :
Hence, the 95% confidence interval for the mean consumption of meat among males over age 50 =(3.3, 3.5)
