The number of calls arriving at a switchboard from noon to 1:00 P. M. during the business days Monday through Fri- day is monitored for 6 weeks (i. e., 30 days). Let X be defined as the number of calls during that one-hour period. The relative frequency of calls was recorded as

Value Relative: 5 6 8 9 10
Frequency Value: 0.067 0.067 0.100 0.133 0.200
Relative Frequency: 0.133 0.133 0.067 0.033 0.067

a. Does the assumption of a Poisson distribution seem appropriate as a probability model for this data? Use α= 0.05.
b. Calculate the P-value for this test.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

the answer is a if my teacher taught me correct

answer: 12,000

step-by-step explanation: first you ar e supposed to add. then multiply then subtract
