Answer:
96 people are expected
Step-by-step explanation:
Hello!
We can first convert the surveyed group results into a percentage.
- 6 people out of 200
- 6/200
- 3/100
- 0.03
- 3%
So 3% of the sampled survey were interesetd. To find the actual expected number of patrons, we find 3% of 3200.
96 people are expected.

Answer with Step-by-step explanation:
Since we have given that
Average per week in sales = $8000
Steve hopes that the results of a trial selling period will enable him to conclude that the compensation plan increase the average sales per salesperson
So, the appropriate null and alternate hypothesis would be
b. What is the Type I error in this situation? What are the consequences of making this error?
Type 1 error are those errors in which null hypothesis are supposed to be rejected, but it does not get rejected.
It means sales per week is greater than $8000 but in actual it is not.
c. What is the Type II error in this situation? What are the consequences of making this error?
Type 2 are error are those errors in which null hypothesis are supposed to be accepted but it get rejected.
It means average sales per week is actually $8000 but it is calculated that average sales is less than $8000.
ANSWER
0.2546
EXPLANATION
The movie theatre's daily revenue, X, is normally distributed with a mean of $3152 and a standard deviation of $1281.
We have to find the probability that the theatre generates more than $4000 in revenue on a randomly selected day,
To find this probability, we have to standardize X using the formula,
So the probability is,
Now, we have to look up this z-value in a z-score table. These tables usually show the area to the left of the z-score - this means that they show the probability for a z less than the z-score, so we have to find the complement,
In a z-score table,
So the probability is,
Hence, the probability that the theatre generates more than $4000 in revenue on a randomly selected day is 0.2546.
