What is the likely effect of treating a sample of DNA with more than one kind of restriction enzyme?
your mom haha your such a looser for putting your mom the answer is treating a DNA sample with more than one kind of restiction enzyme will probably produce more DNA fragments of different sizes
Why was Mendel successful when studying the pea plant?
Because of his background in statistics and physics.
How can a large sample size help minimize instrument errors?
To put it in the simplest possible terms, if errors happen in a small sample size they create a larger discrepancy than in a larger sample size. Let's say you're trying to find average height, for instance, and use 3 people. One is 180cm, one is 190... and the third is 230. Now you've got an average of 2m, which is obviously not true. Let's say you add 2 more people to your sample, both of normal height. (180 and 185) This makes for an average of 193cm, a bit closer to normal. As you get into larger sample sizes this discrepancy from the reading of 230, regardless of whether this is an accurate reading or an error, will get smaller. Also, if you are speaking of some type of electronic or scientific instrumentation, large sample sizes help average out: 1. Electrical noise 2. Variations in measurements due to heat/hysteresis/accuracy of the equipment. 3. Also, don't forget human error in setup, recording, and even variations from one same to the next.
How many car batteries are in a ton weight?

Why the marker lanes are used during electrophoresis?
The marker lanes are important in electrophoresis because in these lanes peptides or proteins with known molecular sizes and weights (standards) run beside, on the same gel, with the sample and the Rfs (relative mobilities) of the developed bands of the unknown proteins can be compared with those of the standards.
Is it necessary that sample sizes be equal for a two sample test?
No.
Where is a good place to shop for cultured pearls?
The Oklahoma Jewelers Association would recommend that the best place to shop for cultured pearls would be at the Pearl Oasis. The Pearl Oasis offers the best cultured pearls available in different sizes.
What size are the sample sizes at fashion shows?
Sample sizes vary from designer to designer but a common range is between 0-2, 4 at most.
In a controlled experiment how do the number of trials and sample sizes effect the results?
The number of trials and sample sizes generally increase the accuracy of the results because you can take the average or most common results in the experiment
Disadvantages of a large sample size confidence Interval in statistices?
A disadvantage to a large sample size can skew the numbers. It is better to have sample sizes that are appropriate based on the data.
When using the distribution of sample mean to estimate the population mean what is the benefit of using larger sample sizes?
The variance decreases with a larger sample so that the sample mean is likely to be closer to the population mean.
Why do smaller populations need larger sample sizes?
They do not. Population size does not affect the sample size. The variability of the characteristic that you are trying to measure and the required accuracy will determine the appropriate sample size.
Does the Student t distribution takes different values for a different sample size?
Yes, but it converges to the Gaussian (Normal) dirstribution for large sample sizes.
What is the largest size bathroom basin?
It is not really known what the largest size bathroom basin is as they will vary around the world and can be custom built to very large sizes. The largest one can get in a traditional store is about 1500mm.
Is it desirable to have a two sample test with equal sizes?
If they are not matched pairs, it does not really matter. If the combined sample size is fixed (because of costs, say) then it is better to have a larger sample where more variability is expected.
What are cultured stones?
Cultured stone is the result of a man-made attempt to replicate the appearance of natural stone. Cultured stone is produced by pouring a cement-like aggregate into molds of various shapes and sizes. The solidified product is then face treated to resemble stones which may be found in nature. The cultured stone is lighter, usually only a slab with one finished face, relatively thin, and is used in facing applications like fireplaces and walls where the weight of a natural stone would cause some concern.
When designing an experiment a benefit of larger sample sizes would be more?
Accurate estimates of various statistics.
