Next, the students at the Pearson Cooking Academy are assigned a take-home written exam to assess their knowledge of all things culinary. Historically, students scores on this exam had a N(68, 36) distribution. However, these days, there is an company called Charred Egg that offers to help students on tasks whether or not the exercises are for homework or for exams. In a cohort of 19 students, what is the probability that their average score will be at least 70?

The probability is  

Step-by-step explanation:

From the question we are told that

    The  population mean is  

      The standard deviation is  

      The  sample size is  

Generally the standard error of the mean is mathematically represented as  

=>        

=>        

Generally the probability that their average score will be at least 70 is mathematically represented as

Generally

So

From the z-table

=>          

=>        

=>          

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

12.5 feet
