An apple farm claims that the average weight of all their apples is 8oz. a sample of 20 apples were picked that had a mean of 7.77oz and standard deviation of 0.95oz. we want to test whether the mean apple weight is different from 8oz. assume that the apple weights are normally distributed.

The mean apple weight is different from 8oz

Step-by-step explanation:

Claim : An apple farm claims that the average weight of all their apples is 8oz.

n = 20

Standard deviation =s = 0.95

Since n < 30

So we will use t-test

x = 7.77

Substitute the values :

Since we are not given the significance level

So, we will take 5%

So,α = 0.05

Degree of freedom = df = n-1 = 20-1 = 19

So, using t table

Since t critical > t statistic

So, we accept the null hypothesis.

So, The mean apple weight is different from 8oz

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
