Amanufacturer of rechargeable laptop batteries markets its batteries as having, on average, 500 charges. a consumer group decides to test this claim by assessing the number of times 30 of their laptop batteries can be recharged and finds the average is 497, with a standard deviation of 10.
the resulting p-value is .; thus, the null hypothesis is not rejected. the consumer group concludes that the manufacturer's claim that its laptop batteries can be recharged, on average, 500 times is accurate.
what type of error is possible in this situation?
twice for joey's age so joeys age is 2 double that it will be 4 so 3+4=7
a) from the function p(t)=6(t), we know that p is 6t, so we plug this into it, to get 3.14 * (6t)^2, or 113.04t^2.
b) using what we got from a), we plug it in and get 113.04 * 8 * 8, or 7234.56 (use a calculator on this, or just bash it with pencil and paper).
