An inspector inspects large truckloads of potatoes to determine the proportion p in the shipment with major defects prior to using the potatoes to make potato chips. unless there is clear evidence that this proportion is less than 0.10, she will reject the shipment. to reach a decision, she will test the hypotheses h0: p = 0.10, ha: p < 0.10 using the large sample test for a population proportion. to do so, she selects an srs of 50 potatoes from the over 2000 potatoes on the truck. then, the normal approximation to the binomial can safely be used for this significance test. the normal approximation to the binomial should not be used for this significance test. the alternative hypothesis should be ha: p > 0.10.

b is the correct answer

among other factors, composers started writing dynamic markings in their scores because "new instruments allowed for more dynamic ranges and contrast."

dynamics allude to the loudness or softness of music. dynamics offer an approach to demonstrate articulation in sheet music. they to drive the enthusiastic substance of music through volume and force. maybe you could alter both the volume and the shading profundity on your screen at the same time. we can likewise think about the force side of elements as the quality of a note. a few notes are intended to be played delicately and gently, while others are intended to be played all the more firmly.  

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.
