Answer:
Step-by-step explanation:
From the given question.
We can write the null hypothesis & the alternative hypothesis as:
Null hypothesis:

Alternative hypothesis:

From above, let's think about the type I error we could make and the type II error we could make.
<u>Type I error:</u>
The type I error at the null hypothesis showcases that the snow level is at 6 inches or below 6 inches, but we falsely concluded that the snow level is high above sea level.
<u>Type II error:</u>
Here, the snow level is literally above 6 inches, hence, we failed to conclude that the snow level is above 6 inches.
Thus, the consequences of the above analysis showcase that type II error has higher severe consequences because it may result in a situation that may endanger the passengers' safety.
Answer:
$16
Step-by-step explanation:
$2 x 5 = $10
1 pound = $9
2/3 = $6
10+6=16
The answer to your questions would be “46 degrees” :) you’re welcome
Answer:
The probability that a randomly selected high school senior's score on mathematics part of SAT will be
(a) more than 675 is 0.0401
(b)between 450 and 675 is 0.6514
Step-by-step explanation:
Mean of Sat =
Standard deviation = 
We will use z score over here
What is the probability that a randomly selected high school senior's score on mathe- matics part of SAT will be
(a) more than 675?
P(X>675)

Z=1.75
P(X>675)=1-P(X<675)=1-0.9599=0.0401
b)between 450 and 675?
P(450<X<675)
At x = 675

Z=1.75
At x = 450

Z=-0.5
P(450<X<675)=0.9599-0.3085=0.6514
Hence the probability that a randomly selected high school senior's score on mathematics part of SAT will be
(a) more than 675 is 0.0401
(b)between 450 and 675 is 0.6514
Answer:
A and B is correct
