Suppose the average wait time for a sandwich at a local deli is 55 min with a standard deviation of 33 min. Is it unusual to wait over 1212 minutes to get a sandwich?

The wait  time is unusual because the probability value obtained is less than 2 standard deviation above the mean

Step-by-step explanation:

From the question we are told that

     The average wait time is  

     The standard deviation is  

Generally the probability of  waiting over 1212 minutes is

So

From z table  the probability of  (Z  >  35 ) is  

Hence

The  time is unusual because the probability value obtained is less than 2 standard deviation above the mean

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
