One of your distributors reports an average of 150 sales per day. you suspect that this average is not accurate, so you randomly select 35 days and determine the number of sales each day. the sample mean is 143 daily sales with a standard deviation of 15 sales. at ? = 0.01, is there enough evidence to doubt the distributor’s reported average? step 1. state the null and alternate hypothesis. step 2. identify the test as left-tailed, right-tailed or two tailed test. step 3. identify the significant level, ? step 4. determine the critical value(s)step 5. identify the rejection and non-rejection region(s)step 6. compute the test statistic (test value)step 7. make the decisionstep 8. interpret the decision.

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.
