Answer:
Option C - Do not reject the null hypothesis. There is not sufficient evidence that the true diameter differs from 0.5 in
Step-by-step explanation:
We are given;
n = 15
t-value = 1.66
Significance level;α = 0.05
So, DF = n - 1 = 15 - 1 = 14
From the one-sample t - table attached, we can see that the p - value of 0.06 at a t-value of 1.66 and a DF of 14
Now, since the P-value is 0.06,it is greater than the significance level of 0.05. Thus we do not reject the null hypothesis. We conclude that there is not sufficient evidence that the true diameter differs from 0.5 in.
Answer:
[0, 57.5]
<em>OR</em>
0 - 57.5
Step-by-step explanation:
Given the function which gives the heart rate as per time.
That means Heart rate of the runner changes according to time.
is a function which takes Time as input as observed by the function's representation. In bracket, there is
.
That also means time is the input to the function
.
It is also given that during the time as the runner runs, the heart beat will change.
The output of the given function will be Heart beat of the runner.
Time taken to complete the run is given as 57 minutes and 30 seconds.
Domain of a function is the valid inputs that can be given to the function for which the output of the function is defined.
Here, time in minutes is the input to the function.
So, maximum time can be 57.5 minutes.
And as the runner will start from the time = 0 minutes
So, the valid inputs can be from <em>0 to 57.5 minutes.</em>
Therefore, the domain is [0, 57.5]
<em>OR</em>
0 - 57.5
