The two-sided alternative hypothesis is appropriate in this case, the reason being we are asked "does the data indicate that the average body temperature for healthy humans is different from 98.6◦........?".

The test statistic is:

Using an inverse normal table, and halving

for a two-tailed test, we look up

and find the critical value to be Z = 2.5758.

Comparing the test statistic Z = -5.47 with the rejection region Z < -2.5758 and Z > 2.5758. we find the test statistic lies in the rejection region. Therefore the evidence does not indicate that the average body temperature for healthy humans is different from 98.6◦.

**Step-by-step explanation:**

**Answer:**

1. 2,323,440 2. 468,544 3. 1,858,752 4. 374,835.2 5. 1,483,917

**Step-by-step explanation:**

SA= 2LW + 2LH + 2WH

To find the cost you would divide the total by 1.25, giving you 3 and 4. Then, you'd subtract the two totals to find 5. I am not 100% sure this is correct but I tried.

Answer:

14 gallons

Step-by-step explanation:

First determine the amount of miles per gallon her car will go by dividing the amount of miles by the amount of gallons.

228/9.5 = 24 miles per gallon

This means on a trip of 336 miles she will use 14 gallons.

336/24= 14 gallons

**Answer:**

1. 8.5 same side as the side on the left (congruent)

2. 65° same as opposite angle (congruent angles)

3. 7.2 E is the midpoint so its the same as that measurement
