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:
Step-by-step explanation:
x² + 4x -21 = x² + 7x - 3x -3*7
= x*(x + 7) -3(x + 7)
=(x + 7)*(x-3)
Answer:9/4
Step-by-step explanation:multiply 2.25 by 100 so you get 225/100 and reduce
Answer:
Step-by-step explanation:
2/3 x - 4 = - 92
add 4 to both sides
2/3 x = - 88
multiply both sides by 3
2 x = - 264
divide both sides by 2
this is ur answer
Good luck
Hope this helps!
