Question

A camping equipment company purchases small light bulbs from another company for use in flashlights. The bulbs are shipped in large lots, with several hundred bulbs in each lot. When a lot is received, a random sample of 50 of the bulbs is selected and tested to see if they are good (i.e., not burned out). If more than 3 of the bulbs in the sample fail to light up when tested, the company rejects the entire lot and returns it to the supplier. Suppose that 3% of the bulbs in a newly shipped lot are defective. Using the sampling plan described above, calculate the probability that this lot will be accepted by the company. Round your answer to at least three decimal places. (If necessary, consult a list of formulas. Also note that the ALEKS calculator allows you to compute binomial probabilities.) x I ?
