Astopwatch is calibrated for a time interval of 1/100th of a second with a range of 9 hours 59 minutes and 59.99 seconds. it also has a ± 5-seconds-a-day bias. this means this watch could gain or lose up to 5 seconds each day of use.

if you use this stopwatch to measure a time of 1 hour 32 minutes and 42.85 seconds, how much time could have actually passed?

exactly 1 hour 32 minutes 42.85 seconds

between 1 hour 32 minutes 42.84 seconds and 1 hour 32 minutes 42.86 seconds

between 1 hour 31 minutes and 1 hour 33 minutes

between 1 hour 32 minutes 37.85 seconds and 1 hour 32 minutes 47.85 seconds

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
