The owner of a local nightclub has recently surveyed a random sample of 300 customers of the club. She would now like to determi

ne whether or not the mean age of her customers is over 35. If so, she plans to alter the entertainment to appeal to an older crowd. If not, no entertainment changes will be made. Suppose she found that the sample mean was 35.5 years and population standard deviation was 5 years. What is the p-value associated with the test statistic

Answer:

0.0416

Step-by-step explanation:

Given :

Sample size, n = 300

Sample mean, x = 35.5

Population mean, m = 35

Standard deviation, s = 5

The test statistic :

Zstatistic = (x - m) / s/sqrt(n)

Zstatistic = (35.5 - 35) / 5/sqrt(300)

Zstatistic = 0.5 / 0.2886751

Zstatistic = 1.732

Using the p value calculator from Zstatistic :

One tailed P value at 95% confidence interval is : 0.0416

Charisse is buying two different types of cereals from the bulk bins at the store. Granola costs $2.29 per pound and muesli cost
valentina_108 [34]
Even though im not giving you grapahs, I can explain you the situation and I can shed you light inot this. Pay attention. Giveen the data we are going to use it like this  <span>2.29x + 3.75y <= 7.00. Remember, you can't spend more money than 7.00, so whatever you buy has to be within 7.00$ or equal 7.00$. Since you're buying in pounds, and the amount varies, you have a variable there to indicate the price of each product depending on how many pounds of it you buy. Now, what you need to do is use this equation to graph and also solving part b by substituting in that value for y. I hope this can help you</span>

True.
The Pythagorean theorem is a^2 + b^2 = c^2 where a^2 and b^2 are the two legs of the triangle (two sides connected by the right angle) and c is the hypotenuse (longest side, opposite the right angle).

To solve using the Pythagorean theorem, plug in sides AC and CB into a and b, then solve for c.

23^2 + 31^2 = c^2
529 + 961 = c^2
c^2 = 1490
c = √1490 = 38.601

I hope this helps!
