Divide 77.5 by 10 = 7.75
Since we divide by 10.2 (and not 10), we **subtract** 2% of 7.75, which is about 0.155 to give 7.595. (error=-0.04%)
You can also simplify a little by approximating 2% of 7.75 as 0.15 to give 7.6 as your estimate. (error=+0.026%)
exact value = 7.598...
1+1+1 is 3. And you have 1/3+1/3+1/3=3/3=1. So you end up with 3+1=4. So yes
Answer:
A one-tailed hypothesis will be used to perform the test.
Step-by-step explanation:
The purpose of the marketing research consultant hired by Coca-Cola is to determine whether the the proportion of customers who prefer Coke to other brands is over 50%.
The marketing research consultant selected a random sample of <em>n</em> = 200 customers. The sample proportion of people who favored Coca-Cola over other brands was 55%.
The marketing research consultant can perform a single proportion hypothesis test to determine whether greater than 50% of customers prefer Coca-Cola to other brands.
Since we need to determine whether the population percentage is greater than a null value, the hypothesis is not two-tailed.
The hypothesis can be defined as:
<em>H₀</em>: The proportion of people who favor Coca-Cola over other brands was 55%, i.e. <em>p</em> = 0.50.
<em>Hₐ</em>: The proportion of people who favor Coca-Cola over other brands was more than 55%, i.e. <em>p</em> > 0.50.
Thus, a one-tailed hypothesis will be used to perform the test.
Answer:
x=2.080084
Step-by-step explanation: take cube root
2 combines = 320 acres
