viktelen [127]

Step 1
find the inverse
exchange x for y and y for x
y=2x
then
x=2y---------> clear y
y=x/2
f−1(x)=x/2

for x=32
f−1(32)=32/2----------> 16

Using the information regarding the proportion of work time linguists study a new language, choose the correct conclusion for th

Vlada [557]

Answer:

The correct option is B

Step-by-step explanation:

From the question we are told that

The null hypothesis is $H_o : p = 0.10$

The alternative hypothesis is $H_a : p > 0.10$

The p-value is $p-value = 0.09$

The level of significance is $\alpha = 0.025$

From the given values $p-value > \alpha$ so we fail to reject the null hypothesis

So there is NOT sufficient evidence to conclude the proportion of work time linguists study a new language is more than 10%.
