Statisticians use sampling plans to either accept or reject batches or lots of material. suppose one of these sampling plans involves sampling independently 10 items from a lot of 100 items in which 12 are defective. let x be the random variable defined as the number of items found defective in the sample of 10. in this case, the random variable takes on the values 0, 1, 9, 10.

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.
