Answer:
The conditional probability that I get four heads given I pulled out the weighted coin = 0.2401
Step-by-step explanation:
Probability of getting 4 heads from 4 trials for a fair coin = 0.5⁴
But given that it is the weighted coin that is pulled out,
The probability of getting 4 heads from 4 trials = 0.7⁴ = 0 2401
Answer:
He confused the height and diameter
Step-by-step explanation:
Given that,
The radius of the cylinder, r = 2.5 cm
Height of the cylinder, h = 24 cm
The volume of the cylinder is given by the formula as follows :

Vaughn is confused in diameter and the height of the cylinder. He takes radius as 12 cm and height as 5 cm which is wrong. Hence, the correct option is (a).
Answer:
Step-by-step explanation:
Given that for a sample size of 25, sample mean = 102 lbs. and sample std deviation = 10 lbs.

(Right tailed test)
Given that we assume population is normally distributed
Test statistic:
Mean difference = +2
Std error of sample = 
t = test statistic = Mean diff/Std error 
degree of freedom
Critical value of t = 1.711
Our test statistic >1.71
Accept alternate hypothesis
Because there is significant difference between the test statistic and test statistic lies above critical value.
