Answer:
option C
Step-by-step explanation:
given,
α = 1 - 0.95 = 0.05
degree of freedom (df) = 17 -1 = 16
critical value
(from t-table)
margin of error = 
=2.120\times \sqrt{\dfrac{25.36^2}{17}+\dfrac{25.183^2}{17}}[/tex]
= 2.120 x 8.6467
= 18.33
Margin of error = 18.33
Point estimation of difference = 
= 36.235
lower limit = 36.235 - 18.33 = 17.91
upper limit = 36.235 + 18.33 = 54.57
hence, the nearest option near to answer is option C
Answer:
0.03125
Step-by-step explanation:
Number of Combinations possible with the Transmitters = 2*2*2*2*2 = 32
Probability that they will use the same settings = 1 - Probability of them using different settings.
= 1 - 32*31/(32^2)
=1 - 992/1024
= 1 - 0.96875
= 0.03125
Answer:
See answer below
Step-by-step explanation:
the ratio of pv against nrt is called compressibility Z and measures the deviation from an ideal gas behaviour . When Z is plotted against pressure for CH₄ for 0°C and 200°C the curves will differ because there are
- negative deviations ( Z decreases) due to intermolecular forces
- positive deviations (Z increases ) due to molecular size of gas particles
then
- at 0°C the negative deviations prevail respect to positive deviations at lower pressures ( so Z drops below the horizontal line first ) and then Z increases when pressure increases since the effect of positive deviation is higher ( then Z increases)
- Nevertheless, at 200°C the effect of intermolecular forces is lower and thus the positive deviations always prevail ( thus you observe only Z increasing(
Odd number probability: 13/25
Multiple of five probability: 4/25
