If you see clearly, the value of x is greater than -1.
i.e. x>-1----------(1)
But -1 is pointed by dark point.
It means x=1----------(2)
If you combine these two, you will get,
![x \geqslant - 1](https://tex.z-dn.net/?f=x%20%5Cgeqslant%20%20-%201)
12.
Like above,
the value of x is smaller than -2.
i.e. x<-2----------(1)
But -2 is not pointed by dark point.
It means x is not equal to -2.
So the final result is x<-2.
Answer:
b. Right-Tailed
Step-by-step explanation:
This hypothesis test have a claim that the proportion of all small businesses that fail is higher than 20%. The alternative hypothesis is then written as:
![H_a:\pi>0.2](https://tex.z-dn.net/?f=H_a%3A%5Cpi%3E0.2)
If the sample outcome gives a test statistic that is higher than the critical value (z>z_c), it will fall in the rejection region and the null hypothesis, that states that the proportion is not different from 20%, will be rejected.
As the rejection region comprises all the values in the right tail, above the critical value, we can conclude this is a right-tailed test.
