I think u use multiplication
I believe the answer is
1.1-(-3.8)=4.9
Answer:
r = 4.908
Step-by-step explanation:
V = 885
height (given in the picture) = 11.7
V = h
V = (3.14)()(h)
885 = (3.14)()(11.7)
885/3.14/11.7 =
Take the square root and you get 4.908.
Total number of songs is
And out of 47, total number's of katy Pery's songs are 17.
So probability that the next song will be the song of Katy Pery is
And therefore probability that the next song is not of Kety's pary's song is
And that's the required answer .
Based on the information given, the correct options will be:
a.) Mary would use the sample standard deviation to calculate a t-statistic.
c.) The value for the degrees of freedom for Mary's sample population is six.
One-sample t-test simply means a statistical hypothesis test that's used for the determination of whether an unknown population mean will be different from the specific value.
In this case, the value of the degree of freedom for the sample will be:
= (n - 1) = 7 - 1 = 6.
Also, it should be noted that Mary would use the sample standard deviation to calculate a t-statistic.
