Not only are giraffes tall, the giraffe is one of the world's heaviest animal. A wildlife biologist believes that, on average, giraffes in Kenya weigh more than 2000 pounds. Twenty giraffes in Kenya were weighted and their average weight was 2075 pounds. Assume this data is normally distributed, the sample is random, and a population standard deviation of 174 pounds.

a. Go through the six steps of hypothesis testing to see if there is evidence to support the biologist's claim at a=0.04.
b. Find the p-value in this situation. What is your conclusion based on the P-value? Is it the same as the conclusion in part a?
c. Find the probability of a type Il error if the true mean weight of giraffes in Kenya is actually equal to 2100 pounds.
d. Find the sample size needed so that the probability found in part cis 0.05.

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.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
