Bicycles for hire at the Durban Beach front are deemed beyond repair when one or both its wheels are damaged. According to current statistics, there is an 8% chance that the front wheel gets damaged and a 12% chance the back wheel gets damaged. What is the probability that a hired bike will be deemed beyond repair, provided that the wheels get damaged independently of each other?
Find the area under the normal curve for z=0 to z=2.25.
. It is claimed that the average age of working students in a certain university is 35 years. a researcher selected a random sample of 25 working students. the computation of their age resulted to an average of 32 years with a standard deviation of 10 years. Does this mean that the average age of the working students is different from 35 years? Use 0.05 level of significance and assume normality in the population.
You will combine two numbers from 0 to 9. One entry will win PHP 6000, out of 100 total entries, if
