Answer:

p(z<0.42) = 0.6628

Step-by-step explanation:

A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. That is to say:

μ = 0

σ² = 1

Using a calculator, we find that:

p(z<0.42) = 0.6628 (See picture attached)

Answer:

0.66276.

Step-by-step explanation:

We are asked to find the approximate value of p(z<0.42) for a standard normal distribution.

Our given expression means the probability of getting a z-score less than 0.42.

We need to find the probability of getting the area corresponding to a z-score less than 0.42 under normal distribution curve.

We will normal distribution table to solve our given problem.

p(z

Therefore, the approximate value of our given expression would be 0.66276.

A graduate student wanted to estimate the average time spent studying among graduate students at her school. She randomly sample
expeople1 [14]

Answer:

B. The width of the confidence interval would be smaller.

Step-by-step explanation:

By reducing the confidence level from 99% to 95%, the student assumes that there is more uncertainty about the new confidence interval than the previous one. That, being said, since the results aren't as certain, the confidence interval is widened towards a central average point because the new interval isn't as accurate.

Therefore, the answer is B. The width of the confidence interval would be smaller.

What is the distance between point A and point B?
Tpy6a [65]

Answer:

\sqrt{45}

Step-by-step explanation:

(5,9) and (2,3)

then by distance formula

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

d²=3²+6²

d²=9+36

d²=45

d =  \sqrt{45 }
