Answer:
The probability of observing a sample mean of 31.1 grams of fat per pound or less in a random sample of 34 farm-raised trout is 0.227
Step-by-step explanation:
Let X be the sample mean of fat in 34 farm-raised trout
The probability of observing a sample mean of 31.1 grams of fat per pound or less in a random sample of 34 farm-raised trout can be stated as:
P(X<31.1 grams) = P(z<z*)
where z* is the z-statistic of sample mean of 31.1 grams fat.
z* can be calculated as follows:
z*= where
- M is the average grams of fat per pound (32)
- s is the standard deviation (7)
- N is the sample size (34)
Then z*= ≈ −0.7497
and P(z<z*) ≈ 0.227
The probability of observing a sample mean of 31.1 grams of fat per pound or less in a random sample of 34 farm-raised trout is 0.227
Answer:
D. 331
Step-by-step explanation:
There are only two numbers that can be multiplied together to get 331.
1 · 331 or 331 · 1
Multiply the height by the base to get the area. 8 x 6 = 48. The area of the first triangle is 48 square inches. 8 x 10 = 80. The area of the second triangle is 80 square inches.
