Answer:
(a) The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.
(b) Since -1.54 > -1.64, therefore we accept H₀.
Step-by-step explanation:
(a)
It is given that the value of test statistic is
We need to test the claim that p<0.18.
Null hypothesis:
Alternative hypothesis:
It is a left tailed test.
Significance level:
The z-critical value for a left-tailed test, for a significance level of α=0.05 is -1.64.
(b)
It is a left tailed test and critical value is -1.64 it means the region on left of -1.64 is rejection region.
The value of z is -1.54 and the critical value is -1.64.
We know that -1.54 > -1.64.
Therefore we accept H₀.
1,2,4,6,7 that’s is the answer
A: To find the rate in feet per minute, we can use the information given.
Every two minutes, the submarine dives 300 feet. So
.
In order to confirm that our rate is correct, we can use the second set of information given.
=
.
Since we know that the rate is 150 feet per minute, we can multiply it by any number of minutes and get the answer of how deep the submarine is. We can use a variable x to represent the number of minutes and y to represent the depth in feet.
There's our equation.
B: It would be more reasonable to use an equation with the rate feet per minute because it is more accurate since the time interval isn't too big.
