The number of contaminating particles on a silicon wafer prior to a certain rinsing process was determined for each wafer in a sample of size 100, resulting in the following frequencies:

Number of particles	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14
Frequency	1	3	3	12	11	15	16	10	12	4	5	3	2	2	1

(a) What proportion of the sampled wafers had at least one particle? At least five particles? (Round your answers to two decimal places.)

at least one particle
at least five particles

(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
strictly between five and ten particles

How would you describe the shape of the histogram?

The histogram is negatively skewed and bimodal.The histogram is positively skewed and bimodal. The histogram is positively skewed and unimodal.The histogram is fairly symmetric and unimodal.The histogram is negatively skewed and unimodal.The histogram is fairly symmetric and bimodal.
