a gym has 275 members 40% are bronze members 28% are silver members the rest are good work out the gold members

statuscvo [17]

STEP 1:
Find % of gold members. Subtract the known % of bronze and silver members from 100%.

x= percent of gold members

x= 100% - (40% +28%)
x= 100% - 68%
x= 32% percent of gold members

STEP 2:
Find number of gold members. Multiply % of gold members by the total numbers of members (275).

x= # of gold members

x= 275 * 32%
x= 275 * 0.32
x= 88 gold members

Hope this helps! :)

According to a study conducted by an organization, the proportion of Americans who were afraid to fly in 2006 was 0.10. A rando

Nimfa-mama [501]

Answer: No, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.

Step-by-step explanation:

Since we have given that

n = 1400

x = 154

So, $\hat{p}=\dfrac{154}{1400}=0.11$

and p = 0.10

So, hypothesis would be

$H_0:\hat{p}=p\\\\H_a:\hat{p}>p$

So, the test statistic value would be

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\z=\dfrac{0.11-0.10}{\sqrt{\dfrac{0.1\times 0.9}{1400}}}\\\\z=\dfrac{0.01}{0.008}\\\\z=1.25$

At 5% level of significance,

critical value would be 1.96.

Since 1.96>1.25.

so, we will accept the null hypothesis.

Hence, no, this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased.
