Define Sample size?
a number of observations in testing something such as medicine, pills, etc.
What is difference between testing and measuring?
testing is a technique or process used to measure the level of achievement or performance measurement refers to the process of quantifying or assigning a number to performance
Explain how both a stock split and a stock dividend affect the computation of the weighted average number of shares outstanding?
Stock splits and stock dividends both affect the Weighted Average Number of Shares Outstanding in the same way. When it occurs, you act as if it happened at the beginning of the year, and throughout previous periods.
Do extremely high or low scores affect the value of the median?
No, extremely high or low values will not affect the median. Because the median is the middle number of a series of numbers arranged from low to high, extreme values would only serve as the end markers of the values.
How does increasing the number of tosses of a coin affect the average size of the deviation?
It's an important principle or probability. The more coin tosses there are, the more chance there is for an expected outcome.
Does the number of batteries change the brightness of the bulb?
It will if the batteries are connected in series. If they are connected in parallel, the lamp will burn longer, but not brighter.
Does the number of batteries affect the speed of a motor?
If they are connected in series the voltages will add and, theoretically, proportionally speed up the motor.
What is the unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
What is the standard unit for apparent brightness?
The apparent brightness of stars is called "apparent magnitude", and it is written with a lowercase "m" after the number.
Factory workers test 60 batteries. 24 batteries are defective. What is the experimental probability that a battery is defective?
Just divide 24 (the number of defective batteries) by 60 (the total number).
How does sun effect batteries?
The sun can have a number of different effects on batteries. The sun can for example either drain or charge different batteries.
What is a stars brightness known as?
A star's brightness is known as its magnitude. Stars with lower magnitude numbers are brighter than stars with a higher magnitude number.
If a circuit has two AA alkaline batteries how many joules of energy does each coulomb of charge?
You need to multiply the number of coulombs by the number of volts. If the two batteries are in series, then you can add the voltage of both batteries.
If you double the brightness of a light source what else doubles?
If you assume linear relation between the brightness and number of photos (linear case; in some cases it's not true) than the number of photons will double too.
Are there environmental benefits to using rechargeable batteries?
Yes, there are big environmental benefits to using rechargeable batteries, especially that there won't be as much toxic materials in waste dumps, because it cuts down on the number of batteries throw away. Rechargeable batteries are extremely environmentally friendly, because they cut down on the number of batteries disposed of each year.
How would you compare the brightness of the bulbs as you increase the number of bulbs?
-- If the bulbs are in parallel, then the addition of a bulb has no effect on the brightness of those that were there before. -- If the bulbs are in series, then the addition of a bulb causes the brightness of those that were there before to decrease. (And I wasn't even there when you did the experiment !)
Where can I get a CSB battery?
There are a number of online retailers that sell CSB batteries. You can locate and compare prices on a variety of brands of CSB batteries at http://www.bizrate.com/batteries/csb-battery/.
