Its 1/3 times 16 times 10.
Answer:
c) tan
Step-by-step explanation:
tan = Opposite side / close side
When close side = v and Opposite side = 2,8m
Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
