Answer: kindly check explanation
Step-by-step explanation:
The Null hypothesis says mean height is 174.1cm
The alternative hypothesis negatea the null hypothesis :
Possible conclusions that can be made about the Null hypothesis. After utilizing the tbe various statistical procedures, we can either stand by the Null hypothesis or we reje t this null Hypothesis.
From the question above, supporting tbe claim that the mean height of men is equal to 174.1 cm is impossible as the expression represents the null claim. Statistical test are only used to support an alternative claim whereby if the test is not significant at certain level of significance x
Alternative hypothesis serves as the claim which requires statistical test on other to establish it's significance.

Answer:
See explanation.
Step-by-step explanation:
We are looking at a geometric distribution.
The probability of selecting a brown peanut is .12 = p
The probability of not selecting a brown peanut is .88 = q
The probability mass function is p(y) = (.88)^(y-1) * (.12)
a) p(7) = (.88)^6 * .12 = .0557
b) p(7 <= y <= 8) = p(7) + p(8)
= .0557 + (.88)^7 * .12 = .1048
c) p(y <= 7) = p(0) + p(1) + ... + p(7)
= .12 + (.88)^1 * .12 + (.88)^2 * .12 + ... + (.88)^6 * .12 = .4713
d) The expect value is 1/p. So, 1/(.12) = 8.33 M&M's

Answer:
Probability = 0.500
Step-by-step explanation:
If it is given that the reader is a teen, we have a total of 80 readers, where 40 of those readers have Rowling as their favorite.
So the probability that the reader's favorite is Rowling given that the reader is a teen is the number of teen readers that have Rowling as favorite (40) over the total number of teen readers (80)
Probability = 40 / 80 = 0.500
