Answer:

The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.

Zaria is going down to the arcade to play

Nana76 [90]

Answer:

I believe that it would be y=$0,25x+$5

Step-by-step explanation:

The initial cost to get into the arcade is $5 so that would be the y-intercept (b) in a slope equation (y=mx+b). Since each game costs $0,25, then that would be the slope (m) and x would be the number of games she played. y would equal the total amount of money spent. So if she played 10 games, substitute 10 for x and multiply by 0,25 and take the answer and add 5 to get the total amount.

You cannot factor it any further as it is in its simplest factored form. There is no common factor in either the term (25x^2) or (9y^2) that you can pull out so it cannot be simplified. Hope this helps

The director of research and development is testing a new medicine. She wants to know if there is evidence at the 0.05 level tha

Nataly [62]

Answer:

a. There is sufficient evidence at the 0.05 level of significance that the medicine relieves pain in more than 325 seconds.

Step-by-step explanation:

With the info provided let the parameter of interest $\mu$ who represent the mean that the medicine relieves pain, the system of hypothesis would be:

Null Hyp: $\mu \leq 325$

Alternative Hyp : $\mu >325$

If we know the population deviation, is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:

$z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}$

z-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".

If the deviation is not known we can use the t test with the following statistic:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$

On this case the decision was REJECT the null hypothesis. That means that we obtain a significant result with a p value lower than the signficance level

$p_v$

So then we can conclude this:

a. There is sufficient evidence at the 0.05 level of significance that the medicine relieves pain in more than 325 seconds.
