Answer: -5<-8
Step-by-step explanation:
Part A: 5 out 25 lobsters have dangerous levels of mercury
Part B: the 95% confidence interval is given by (4.45, 5.65)
since everything is given all I had to do is find the critical value which can be found from the resource packet = 2.064
Using the formula we find 5.05+-2.064*1.45/5 = ( 4.45,5.65)
For this case, we have 95% of confidence that the true mean for the average number of lobsters with dangerous levels of mercury is between 4.45,5.65
Answer:
We conclude that everyone should receive 2/3 cookie.
Step-by-step explanation:
We know that everyday Mary and Laura walk to Mrs. Peterson's house to visit her. She always gives them each a Swedish cookie. One day when Mary and Laura walked home, they decided they would share their cookies with Baby Carrie.
They have a total of 2 cookies. So 2 cookies should be divided into 3 equal parts.
We calculate 2/3=0.666.
We conclude that everyone should receive 2/3 cookie.
