By production of one type of lightbulb at a factory is the probability for a lightbulb to be defective 1%. Four lightbulbs is choosen undependent of each other, and is sold as a package.

a) What is the probability that there is no defective lightbulbs in a package?
b) What is the probability that there is excactly one defective lightbulb in the package, if there is defective lightbulbs in the package?

A business recives 50 packages of 4 lightbulbes from this factory

c) What is the probability that there is in average more than 0.1 defective lightbulbs in the 50 packages?
d) What is the probability that there is at least one defective lightbulb in the 50 packages?

The manager of a lightbulb factory wants to determine if there is any difference in the mean life expectancy of the bulbs manufactured on two different types of machines. A random sample of 4 lightbulbs from machine I indicates a sample mean of 352 hours and a sample standard deviation of 98 hours, and a similar sample of 4 lightbulbs from machine II indicates a sample mean of 364 hours and a sample standard deviation of 125 hours.

In a factory, it is known that the probability of fixing a particular production error is 1/3. For production of 10 units with this error; a-)Write the probability function. b-)What is the probability that all three can be corrected? c-)What is the probability that one of the most errors can be fixed? d-)What is the probability that two or more errors can be corrected? e-)What is the probability that more than three, 5 or fewer errors can be corrected?

The life in hours of a certain type of lightbulb is normally distributed with a known standard deviation of 10 hours. A random sample of 15 lightbulbs has a sample mean life of 1000 hours. What would the 99% lower-confidence bound L on the mean life be, rounded to the nearest integer?

In order to determine the life expectancy of a particular type of lightbulb manufactures by a lighting company, the corporate quality control officer randomly selected 10 bulbs from the pre-packaging section of the company's production line. The bulbs were subsequently tested in the quality control lab and the following data was recorded. Bulb Life(Hours) 1 3900 2 4200 3 4100 4 3800 5 4000 6 4300 7 3600 a. Calculate the mean life of bulbs in this sample. Mean= b....

A lightbulb manufacturer has developed a new lightbulb that it claims has an average life of more than 1,000 hours. A random sample of 50 lightbulbs was taken and had a mean of 1,065 hours and standard deviation of 125 hours. Perform a hypothesis test with a level of significance of 0.01. Perform steps 2 and 3 of the hypothesis test. Perform step 4 of the hypothesis test using the information from the last question. Perform step 5 of the...

A lightbulb manufacturer ships large consignments of lightbulbs to big industrial users. When the production process is functioning correctly, which is 90 % of the time, 35% of all bulbs produced are defective. However, the process is susceptible to an occasional malfunction, leading to a defective rate of 80%. If a defective bulb is found, what is the probability that the process is functioning correctly? If a nondefective bulb is found, what is the probability that the process is operating...

Q8. One store notes that the probability of some type of error in a telephone order is 0.2. A supervisor randomly selects telephone orders and carefully inspects each one. (2pts) What is the probability that the third telephone order selected will be the ﬁrst to contain an error? (3pts) What is the probability that the supervisor will inspect between two and six (inclusive) telephone orders before ﬁnding an error? (3pts) What is the probability that the inspector will examine at...

Match the described probability with the type of probability. It is estimated that 75% of a grapefruit crop is good. The other 25% have rotten centers once the grapefruit is cut open. Therefore, the grapefruit can either be good or bad for consumption. You randomly select 10 grapefruits and are asked to find the probability that are exactly 5 are good. A vending machine automatically pours soft drinks into cups. The amount of soft drink dispensed into a cup is...
