Consider a value to be significantly low if its z score less than or equal to 2 or consider a value to be significantly high if its z score is greater than or equal to 2. A data set lists weights (grams) of a type of coin. Those weights have a mean of g and a standard deviation of g. Identify the weights that are significantly low or significantly high.
What weights are significantly low? Select the correct answer below and fill in the answer box(es) to complete your choice.
A.
Weights that are less than
nothing. (Round to five decimal places as needed.)
B.
Weights that are greater than
nothing. (Round to five decimal places as needed.)
C.
Weights that are between
nothing and
nothing. (Round to five decimal places as needed. Use ascending order.)

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
