(Round your answers to two decimal places) at least one particle at least five particles 0.70 (b) What proportion of the sampled wafers had between five and ten particles, inclusive? Strictly between five and ten particles? (Round your answers to two decimal places.) between five and ten particles, inclusive 0.60 strictly between five and ten particles 0.40 (e) Draw a histogram using relative frequency on the vertical axis Percent Percent 10 Number 01234567 8 910111213 14 012345678 910111213 14 Percent Percent 15 7 5 6 8Explanation / Answer
a) at leat one particle = 0.99
at least 5 partcles = 1 - less than 5
P = 1 - 28/100
P = 0.72
b) 5 and 10 inclusive:
P = 65/100 = 0.65
Strict between 5 and 10:
P = 45/100 = 0.45
c) D option
