Answer:
yes it is less then a right angle
Step-by-step explanation:
Answer:
A. The larger the sample size the better.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
We have to look at the standard error, which is:
This means that an increase in the sample size reduces the standard error, and thus, the larger the sample size the better, and the correct answer is given by option a.
Answer:
=94 cm
Step-by-step explanation:
Using the Triangle angle bisector theorem
We can find the value for YK
TV VY
------- = -----------
TK YK
95.2 34
------- = -----------
168 YK
Using cross products
95.2 * YK = 34* 168
Divide each side by 95.2
YK = 34* 168/95.2
YK =60
We want to find VK
VK = VY+YK
= 34+60
=94 cm
