What is the distance between the points (1, -4) and (1, 0)
tino4ka555 [31]

For this case we have that the distance between two points is given by:


d = \sqrt{(y2-y1)^2+(x2-x1)^2}

Given the points:


(x1, y1) = (1, -4)(x2, y2) = (1,0)

We substitute in the formula:


d = \sqrt{(0 - (- 4)) ^ 2 + (1-1) ^ 2}

d = \sqrt{(4 ^ 2 + 0 ^ 2)}

d=\sqrt{16}

d = 4

So, the distance is d = 4

Answer:


d = 4

A researcher reports a 98% confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be [0.34,
Fantom [35]

Answer:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

Step-by-step explanation:

For this case we have a confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be given by:

0.34 \leq p \leq 0.38

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.
