Answer:
b. Right-Tailed
Step-by-step explanation:
This hypothesis test have a claim that the proportion of all small businesses that fail is higher than 20%. The alternative hypothesis is then written as:
If the sample outcome gives a test statistic that is higher than the critical value (z>z_c), it will fall in the rejection region and the null hypothesis, that states that the proportion is not different from 20%, will be rejected.
As the rejection region comprises all the values in the right tail, above the critical value, we can conclude this is a right-tailed test.
12 bouquets.
12 is the only number that is divisible by 24, 60, and 84. So that is your only option.<span />
Answer:
first one is −6
second one is 4
third one is 1.5
fourth one is -4
Step-by-step explanation:
Solve for x. The multiplicity of a root is the number of times the root appears.
x= -6.847415 (multiplicity of 1)
x= 0.793705 (multiplicity of 1)
Product: 787 = 1 x 787 = 787
Largest sum: 1 + 787 = 788
