In a fast food study a researcher finds that mean sodium content of 32 wendy's fish sandwiches is 1080 milligrams with a standard deviation of 75 milligrams. the mean sodium content of 39 long john silver's fish sandwiches is 1120 milligrams with a standard deviation of 100 milligrams. at a = 0.05 is there enough evidence for the researcher to conclude that the wendy's fish sandwich has less sodium than the long john silver's fish sandwich?

Since 95% confidence interval contains 0 we conclude at 95% confidence level that the two means are equal.

Step-by-step explanation:

Given that in a  fast food study a researcher finds that mean sodium content of 32 Wendy's fish sandwiches is 1080 milligrams with a standard deviation of 75 milligrams. The mean sodium content of 39 Long John Silver's fish sandwiches is 1120 milligrams with a standard deviation of 100 milligrams

H0: The two means are equal

Ha: The two means are not equal

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
