Answer:
We conclude that the population mean is 24.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 24
Sample mean, 
= 22.8
Sample size, n = 100
Alpha, α = 0.05
Sample standard deviation, s = 8.3
First, we design the null and the alternate hypothesis
We use Two-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
We calculate the p-value with the help of standard z table.
P-value = 0.1498
Since the p-value is greater than the significance level, we accept the null hypothesis. The population mean is 24.
Now, 
Since, the z-statistic lies in the acceptance region which is from -1.96 to +1.96, we accept the null hypothesis and conclude that the population mean is 24.
Answer:
B
Step-by-step explanation:
y = mx + b
The slope is m.
If it was anything other than 0, the line would have an x in it. The line does not have an x associated with it.
The equation of the line is y = 1
The slope must be 0.
-1/2 / 3/4 =
The first step is to flip the second fraction and change division to multiplication. Then multiply straight across.
-1/2 x 4/3 = -4/6
In simplified form:
-4/6 = -2/3
Answer:
Cuanto dinero voy a pagar 24 $
Cuanto recibiré de cambio 76 $
Step-by-step explanation:
Mis compras son:
1 lápiz 3,50 $
2 plumas 7,90 $
1Libreta 12,60 $
Lo que quiere decir que compre:
3,50 + 7,90 + 12,60 = 24 $
Si cancelo mis compras con un billete de 100 $ me tienen que dar vuelto por:
100 $ - 24 $ = 76 $
Answer:
60=3/4
x=4/4
4/4÷1/4
4/4*4/1
4/1*1/1
4/1
4
3/4=12 because if 1/4 is 4 then 3/4 is 12
60=12
60÷12=5
5*4/20
60+20=80
