Assume that when adults with smart phones are randomly selected 44% of them use them in meetings or classes if 12 adult smartphone users are randomly selected find the probability that fewer than 4 of them use their smart phones in meetings or classes
A population of 25 year- old female has a mean salary of P20,800 with a standard deviation of P1200. If a random sample of 10 is considered from the population, what is the probability that their salary is greater than P20900?
If a farmer is chosen randomly from this community, what is the probability that he grows neither oranges nor lemon
An average tire used by a transportation company lasts 20,000 km with a standard deviation
of 100 km. Assuming that the distance traveled by a tire is normally distributed, what is the
probability that a tire used by the company will last at most 30,000 km?
A researcher claims that the average salary of a private school teacher is greater than P35,000 with
a standard deviation of P7,000. A sample of 35 teachers has a mean salary of P37,000. Test the
claim of the researcher. At 0.05 level of significance, test the claim of the researcher.
