The price of lettuce was $1.25 one week and $1.50 the next week.  Find the percent of increase.
melomori [17]
So the lettuce went up by 0.25 or 25c, now, if we take 1.25 to be the 100%, how much is 0.25 in percentage off of it?

\bf \begin{array}{ccllll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;1.25&100\\&#10;0.25&x&#10;\end{array}\implies \cfrac{1.25}{0.25}=\cfrac{100}{x}\implies x=\cfrac{0.25\cdot 100}{1.25}

ankoles [38]

Answer:

Our population of interest represent all the adults in United states who never travel using commercial airlines.

The sample on this case represent the people surveyed in United States who never travel using commercial airlines.

For this case the value obtained \hat p =0.33 represent a statistic since is a value who represent the sample not the population. Our population parameter is not known and is given by p

Step-by-step explanation:

A statistic is a "characteristic of a sample". And the statistic allows "estimate the value of a population parameter".

A parameter is a value who represent the population of interest.  

For this case we have a sample size of size n = 2276

The proportion estimated \hat p of people that nevel travel using commercial airlines was:

\hat p = \frac{x}{2276}=0.33 or 33%

Our population of interest represent all the adults in United states who never travel using commercial airlines.

The sample on this case represent the people surveyed in United States who never travel using commercial airlines.

For this case the value obtained \hat p =0.33 represent a statistic since is a value who represent the sample not the population. Our population parameter is not known and is given by p
