1. The null is the equality (always the equality). The alternative is what is to be shown, so that the
mean is greater than 16.
2. z = (17.1-16)/(6/sqrt(43)= 1.20.
3. 1 table value for 1.20 is 1-.8849 = .1151. This is bigger than the

1. The claim is that the mean is greater than 850, so the alternate hypothesis is too.
2. The null hypothesis is always an equality, so mean =850.
3. P value is greater than the significance level, so the results are not significant a

1. The standard deviation decreases as the sample size increases and the mean of the sample
proportion is the population proportion.
2. The expected value of the sample proportion is the population proportion, so .45.

1. 95% are within +/- 2 standard deviations of the mean, so 32 2*7 to 32+2*7 or 18 to 46.
2. Standard score = (value-mean)/SD , so (21.5-32)/7 = -10.5/7 = -1.5
3. 2.1=(value-32)/7 , so 2.1*7 = value-32, so value = 32+2.1*7 (Note that
