Answer:
A
Step-by-step explanation:
In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.
The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.
Since 0.85 is already in decimal form, leave it as it is.
3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:
Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.
91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.
Now that you can see the numbers, just rearrange them from least to greatest
0.75<0.85<0.91
equal to A
Answer:
We can calculate the p value using the fact that we are conducting a right tailed test:
Since the p value i approximately 0 we can conclude that we have enough evidence to say that with this method, the probability of a baby being a boy is significantly greater than 0.5
Step-by-step explanation:
Information given
n=172+39=211 represent the sample size
X=172 represent the number of boys in the sample
estimated proportion of of boys
is the value to verify
z would represent the statistic
represent the p value
Hypothesis to test
The ides is verify if with this method, the probability of a baby being a boy is greater than 0.5, so then the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
The statitic is given by:
(1)
Replacing the info we got:
We can calculate the p value using the fact that we are conducting a right tailed test:
Since the p value i approximately 0 we can conclude that we have enough evidence to say that with this method, the probability of a baby being a boy is significantly greater than 0.5
