Fiona is not very smart so should know herself what frequency table she should use for her histogram
Answer:
0.8686 or 86.86 %
0.2148 or 21.48 %
Step-by-step explanation:
In z table the value of z > - 1,12 is 0.1314 (value from the z point to the left of the curve ) then 1 - 01314 will be value from z point to the right
Again from z table we get for z = - 0.79 the value 0.2148 s the vale from the point up to the left tail
43 units
count all the square boxes. count the boxes covering more than half and leave the boxes covering less than half. I hope it's correct.
