Answer:
less likely
Step-by-step explanation:
Probability is between 0 and 1 so 1 is guaranteed to happen and 0 is guaranteed to not happen
Answer:
The value of H is 28.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(H-6)/(-7-(-5))
m=(H-6)/(-7+5)
-11=(H-6)/-2
-11(-2)=H-6
22=H-6
H=22+6
H=28
Answer:
97
Step-by-step explanation:
5 * 85 - 4* 82 = 97
Answer:
the probability that five randomly selected students will have a mean score that is greater than the mean achieved by the students = 0.0096
Step-by-step explanation:
From the five randomly selected students ; 160, 175, 163, 149, 153
mean average of the students = 160+175+163+149+153/5
= mean = x-bar = 800/5
mean x-bar = 160
from probability distribution, P(x-bar > 160) = P[ x-bar - miu / SD > 160 -150.8 /3.94]
P( Z>2.34) = from normal Z-distribution table
= 0.0096419
= 0.0096
hence the probability that five randomly selected students will have a mean score that is greater than the mean achieved by the students = 0.0096
where SD = standard deviation = 3.94 and Miu = 150.8
