**Answer:**

80,023,904

**Step-by-step explanation:**

Just add all the numbers together.

4 and a half ducks.

That's pretty much the answer.

**Answer:**

72

**Step-by-step explanation:**

From 1-60, 4 and 6 a few common multiples. Find those multiples, which are

12, 24, 36, 48, 60.

So in 60 seconds, they blink together 5 times.

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
