The t-value given the following: hypothesis test on population mean is -2.
<h3>What is T- value ?</h3>
T-value in statistics can be defined as the ratio of the difference between the mean of the two sample data and the variation in the sample data
It is given by
Here in the question all the values are given
x= 33; μ = 35; s = 5; n = 25.
Substituting the values to determine t
Therefore the t-value given the following: hypothesis test on population mean is -2.

I think it's s>2
Divide -4 and -8 by -4, this flips the sign, and leaves s and 2 behind
Answer:
1. d=m/v
=57.6/112.9
=0.51018601
=0.510g/cm³(3s.f.)
2. m=d×v
=1.8×54
=97.2g
3. v=m/d
=63.8/12.7
=5.02362205
=5.02cm³(3s.f.)
4. v=length×breath×height
=12×2×6
=144m³
216g=0.216kg
d=m/v
=0.216/144
=0.0015kg/m³
Step-by-step explanation:
density=mass/volume
mass=density×volume
volume=mass/density
*make sure the units are correctly placed.
*g/cm³, kg/m³
Answer:
The answer is $3600 I hope this is helpful.
Answer:
64
Step-by-step explanation:
surface area of the cube =96
suppose one side of the cube = a
volume of the cube(V) =?
surface area = 6a^2
6a^2=96
a
^2
=96/6
a^2=16
a = 4
SO
V=
a^
3
V=64.
