Answer:
hello! i can answer in the comments if you tell me what the lengs are and where they are located! i cannot see the picture due to my school computer blocking images on the site so that's why i need the explanation. thanks :>
It is important to clearly understand all the important information's already given in the question. Based on those details the answer to the question can be easily determined.
In 17 hours the number of golf balls hit by Bill = 323
Then
In 1 hour the number of golf balls hit by Bill = (323/17) * 1
= 19
So
The number of golf balls hit by Bill in 23 hours = 23 * 19
= 437
So 437 balls will be hit by Bill in 23 hours. I hope the procedure is clear enough for you to understand. This procedure will help you to solve similar problems in future without requiring any outside help.

You aren't even giving 200 points.
Step-by-step explanation:
Answer:
A
The correct option is B
B

C

D
The correct option is D
Step-by-step explanation:
From the question we are told that
The sample size is 
The number that developed nausea is X = 50
The population proportion is p = 0.20
The null hypothesis is 
The alternative hypothesis is 
Generally the sample proportion is mathematically represented as


Generally the test statistics is mathematically represented as
=> 
=> 
=> 
The p-value obtained from the z-table is

Given that the
then we fail to reject the null hypothesis
Part a)
The simple random sample of size n=36 is obtained from a population with

and

The sampling distribution of the sample means has a mean that is equal to mean of the population the sample has been drawn from.
Therefore the sampling distribution has a mean of

The standard error of the means becomes the standard deviation of the sampling distribution.

Part b) We want to find

We need to convert to z-score.

Part c)
We want to find

We convert to z-score and use the normal distribution table to find the corresponding area.

Part d)
We want to find :

We convert to z-scores and again use the standard normal distribution table.
