Help with what im so confused
Answer:
Step-by-step explanation:
H0 : μ = 46300
H1 : μ > 46300
α = 0.05
df = n - 1 = 45 - 1 = 44
Critical value for a one tailed t-test(since population standard deviation is not given).
Tcritical = 1.30
The test statistic :(xbar - μ) ÷ (s/sqrt(n))
The test statistic, t= (47800-46300) ÷ (5600√45)
t = 1500
t = 1500 / 834.79871
t = 1.797
The decision region :
Reject H0: if t value > critical value
1. 797 > 1.30
Tvalue > critical value ; We reject H0
Hence, there is sufficient evidence to conclude that cost has increased.
<span>the answer is 3 s– 4 </span>
a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
Step-by-step explanation:
Given,
Price of one adult ticket = a = $25
Price of one youth ticket = y = $12.50
Maximum people that can be hold by theater = 1000
Therefore;
The maximum number of people can be 1000 or less than that.

As they want to revenue to be more than 15,000 therefore,

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
