= 0.10606
Step-by-step explanation:
Since we have only one digit in the numerator and the denominator has 2 digits, we have to 0 along with 7, so that it becomes 70, 1 time 66 is 66, 70 - 66 = 4 is the remainder, so the quotient is 0.1, then along with 4 we have to add one 0 , so it becomes 40 which is lesser than 66 so one more 0 is added and then it becomes 400, 6 times 66 is 396, 400 - 396 = 4 again the process going on. The quotient is 0.10606...
Answer: 0.9088
Step-by-step explanation:
Given :
Let x be a random available that represents the proportion of students that reads below grade level .
Using , for x= 0.36 , we have
Using standard normal z-value table,
P-value
[Rounded yo the nearest 4 decimal places.]
Hence, the probability that a second sample would be selected with a proportion less than 0.36 = 0.9088
