Multiply the variable k times 4 would give you 4k.
Then cross multiply 14x8 = 112
Therefore, you would have 4k = 112.
Divide 112 by 4 to get your answer!
Answer:
D. Chi-square test for two-way table
Step-by-step explanation:
To test if there is an association between the percentage of people that successfully stop smoking and the method they used to do so, a random sample of 584 smokers who tried to quit smoking and was orted by the method they used to help themselves to achieve their goal (nicotine-patch or e-cigarettes). After six months, the proportion of subjects that successfully stopped smoking.
In this case, the t-test is not applicable, this statistic is to test the population mean. The variable of the study is the proportion of people that successfully stopped smoking using either method.
To apply Chi-Square tests the condition to be met is that the variable is categorizable and since the data can be organized in a 2x2 table, all expected frequencies should be >5.
The objective of the Goodness-to-fit test is to test if a population follows a certain theoretical model.
In this example, the objective is to compare the proportion of people that successfully quit smoking and the proportion of people that failed by using either method.
Answer:
6 hotdogs
Step-by-step explanation:
1.00d + 1.75h <_ (less than or equal to) 18
Now substitute in 6 for d
1.00(6) + 1.75h <_ 18
6.00 + 1.75h <_ 18
-6 -6
1.75h <_ 12
/1.75 /1.75
h <_ 6.85
We'll round to 6 because you can't have .85 of a hotdog!
Hope this helps!!!
