Answer:
We can assume that the statistic is 
So the p value obtained was a very high value and using the significance level given 
we have 
so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the true proportion of interest is not different from 3/5
Step-by-step explanation:
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the true proportion is equal to 3/5 or not.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statistic, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion 
is significantly different from a hypothesized value 
.
Calculate the statistic
We can assume that the statistic is
Statistical decision
It's important to refresh the p value method or p value approach . "This method is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.
The significance level provided . The next step would be calculate the p value for this test.
Since is a bilateral test the p value would be:
So the p value obtained was a very high value and using the significance level given we have so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the true proportion of interest is not different from 3/5
Answer:
In mathematics, a function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.
I hope this is the correct way to solve one of these.
first you need to know how the graph is so you consider y=x²-8x+17 (you might want to see the picture below to understand in a better way)
then you have to evaluate two points. one above the curve and one underneath the curve to see where y is greater than the curve. so let’s try for instance (0,0) and (4,2)
finally you must determine which points confirm that the statement is actually true. then you select the region for your solution :)
Using conversion of units, it is found that Dylan needs another 1.29 ounces of cheese.
----------------------------
- The conversion of units are applied using a rule of three.
- Each gram has 0.035274 ounces. How many ounces are there in 150 grams?
1 gram - 0.035274 ounces
150 grams - x ounces
Applying cross multiplication:
----------------------------
- Dylan has 4 ounces of cheddar cheese.
- He needs 5.29 ounces.
- Thus, he needs another 5.29 - 4 = 1.29 ounces.
