F. Compute of the variance sampling distribution of the sample means
The quantity produced daily at the ABC cement factory is approximately normally
distributed with mean 0.82 and standard deviation 0.14. The units are on millions of tons.
Find the probability that the total production will between 0.80 and 0.85 million tons.
In 15 experiments studying electrical behavior of single cells 11 use microelectrodes
made of metal and the other 4 use microelectrodes made from glass tubing. If 2 of the
experiments are to be terminated for financial reasons and they are selected at random.
What are the probabilities that
a. Neither uses microelectrodes made from glass tubing?
b. Only one use microelectrodes made from glass tubing?
Let D represent the defective cellphone and N represent the non-defective cellphone. If we let X be the random variable representing the number of defective cell phones, show the values of random variable X? Complete the table below the values of the random variable.
The shelf life of a particular dairy product is normally distributed with a mean of 12 days and a standard deviation of 3 days.
About what percent of the products last between 12 and 15 days?

If the basketball team will play for three (3) consecutive games. If W stands for win and L for loss. What is the possible outcome and the number of random variable representing by wins
A researcher used a developed problem-solving test to randomly selected 50 Grade-11 students. In this sample, X ̅=80 and s=10. The mean and standard deviation of the population used in the standardization of the test were 75 and 15, respectively. Use the 95% confidence level. What is the computed test statistic?
You play game of tossing an unbiased coin.on each toss if a head appears on each toss, you win php.60 .however , if a tail appears you lose php 70. If you continue to play the game, how much do you expect to win or lose in the game
The probability that a blade manufactured by a factory is defective is 1/500. Blades are
packed in packets of 10 blades. Find the expected number of packets containing (i) no
defective blade (ii) one defective blade (iii) 2 defective blades, in a consignment of 10000
packets.
How can we solve this by using only poison distribution
