Consider the test ?0:????−????=3H0:μnew−μold=3 vs. ?0:????−????<3H0:μnew−μold<3 What is the p-value? (Hint: best to use software, or else the Desmos Calculator for the 2 sample T and Z test) Give as a decimal between 0 and 1 accurate to at least 4 decimal places.
A new material will replace the old material unless there is significant evidence that the
Sample from new material: mean is 106.122 , SD is 4.7 and
Sample from old material: mean is 106.449 , SD is 6 and sample size is 60
We do not know population standard deviations.
Consider the test
?0:????−????=3H0:μnew−μold=3 vs. ?0:????−????<3H0:μnew−μold<3
What is the p-value? (Hint: best to use software, or else the Desmos Calculator for the 2 sample T and Z test)
Give as a decimal between 0 and 1 accurate to at least 4 decimal places.
