an electrical company claims that an average life of bulbs it manufactures is 1200 hours with standard deviation of 250 hours.If a random sample of 100 bulbs is chosen, what is the probability of the sample mean will be:
a.Greater than 1150 hours?
b.Less than 1250 hours?
c.Between 1150 and 1250 hours?
A cone of radius r centimetres and height h centimetres iss lowered first at a rate of 1 cm/s into a tall cylinder of radius R that is partially filled with water. How fast is the water level rising at the instant the cone is completely submerged?
A heat engine absorb 750J of heat from a hot performs 265J of work calculate the efficiency of the heat engine.
Compare and contrast any two of radio waves,microwave,infrared,visible light,ultraviolet,x-ray and gamma ray in terms of properties.
In a paper presentation, the average algebraic reasoning of Grade 8 students in a mathematics camp was observed to be 80 with lowest and highest observed value of 20 and 38.4. A researcher wants to replicate the study to estimate the true population mean to within 0.7 maximum error. If the 94% level of confidence is adopted, how many respondents are needed?
