Fantom [35]

Answer:

Step-by-step explanation:

They form a straight line so the y sum to 180

52+58+q = 180

Combine like terms

110+q = 180

Subtract 110 from each side

q = 180-180

q = 70

suter [353]

Answer:

The probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is P=0.412.

Step-by-step explanation:

We know the population proportion π=0.8, according to the 2011 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation.

If we take a sample from this population, and assuming the proportion is correct, it is expected that the sample's proportion to be equal to the population's proportion.

The standard deviation of the sample is equal to:

$\sigma_s=\sqrt{\frac{\pi(1-\pi)}{N}}=\sqrt{\frac{0.8*0.2}{500}}=0.018$

With the mean and the standard deviaion of the sample, we can calculate the z-value for 0.79 and 0.81:

$z=\frac{p-\pi}{\sigma}=\frac{0.79-0.80}{0.018} =\frac{-0.01}{0.018} = -0.55\\\\z=\frac{p-\pi}{\sigma}=\frac{0.81-0.80}{0.018} =\frac{0.01}{0.018} = 0.55$

Then, the probability that between 79% and 81%of the 500 sampled wildlife watchers actively observed mammals in 2011 is:

$P(0.79$

Open Tornadoes-HW6 data. Test if there is a significant difference between the number of tornadoes in August and the number of t

jenyasd209 [6]

Answer:

Use Two sided t-test

Step-by-step explanation:

Note that, there are other tools to test for significant difference such as simple regression or multiple regression but when comparing the results of two groups in terms of which is higher or lower, then a two sided t-test would be best appropriate.

Since we want to know if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average we use the two sided t-test because a Two sided t-test can show the possibility of positive or negative differences.
