Each person in a simple random sample of 1,200 received a survey, and 325 people returned their survey. How could nonresponse
cause the results of the survey to be biased?
A. Those who did not respond reduced the sample size, and small samples have more bias than large samples.
B. Those who did not respond may differ in some important way from those who did respond.
C. Those who did not respond caused a violation of the assumption of independence.
D. Those who did not respond are indistinguishable from those who did not receive the survey.
E. Those who did not respond represent a stratum, changing the random sample into a stratified random sample.

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

question:

could we have options?

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
