A resercher is wondering whehter the drinking habits of adults in a certain region of the country are in the same proportion as

the general population of adults. Suppose a recent study stated that the proportion of adults who reported drinking once a week or less in the last month was 0.26. The researcher's null hypothesis for this test is H0: P=0.26 and the alternative hypothesis is Ha; P> 0.26. The researcher collected datat from a random sample of 75 adults in the region of interest.
1- Verify that the normality assumption is satisfied. Describe each separately.
2- To cotinue the study into the drinking habits of adults, the researcher decides to collect datat from adults working in "blue collar" jobs to see whether their drinking habits are in the same proportion as the general public. The null hypothesis for this test is H0: P=0.26 and the alternative hypothesis is Ha: P>0.26. The researcher computer the test statistic to be 1.59. Draw a graph of z distribution, label the test statistic and shade the p-value associated with this test statistic.

Answer:

\boxed{\sf \ \ \ m = -\dfrac{tn}{t-s} \ \ \ }

Step-by-step explanation:

Hello,

let s assume that m+n is different from 0

we have this equation and we need to find m as a function of t, s, and n

t=\dfrac{ms}{m+n}

<=>

(m+n)*t=ms\\\\ tm+tn=sm\\ (t-s)m = -tn\\ m = -\dfrac{tn}{t-s}

for t-s different from 0, so t different from s

hope this helps

A theater company charges $10.50 per ticket for people of all age groups. If c represents the total number of children who bough
statuscvo [17]

The equation t = 10.5(c + a) represents the total money earned by the company from the sale of tickets

<u>Solution:</u>

Given that,

Ticket charged for people of all age groups = $ 10.50 per ticket

Let "c" represents the total number of children who bought tickets

Let "a" represents the total number of adults who bought tickets

Now, let the total money collect be represented by "t"

Number of people bought tickets = number of children bought tickets + number of adults bought tickets

<em><u>Now the total money earned by company is given as:</u></em>

Total money earned = cost per ticket x number of people bought tickets

Total money collected = cost per ticket x (number of children bought tickets + number of adults bought tickets)

Substituting the known values we get,

\mathrm{t}=10.5 \times(\mathrm{c}+\mathrm{a})

t = 10.5(c + a)

Hence, the required equation is t = 10.5(c + a)
