Answer:
We see that the p value is lower than the significance level given of 0.01 so then we can conclude that the true mean for the nicotine content is significantly higher than 40 mg
Step-by-step explanation:
Information provided
represent the average nicotine content
represent the sample standard deviation
sample size
represent the value to check
represent the significance level for the hypothesis test.
t would represent the statistic
represent the p value for the test
System of hypothesis
We want to verify if the nicotine content of the cigarettes exceeds 40 mg , the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic for this case would be:
(1)
And replcing we got:
The degrees of freedom are:
The p value would be:
We see that the p value is lower than the significance level given of 0.01 so then we can conclude that the true mean for the nicotine content is significantly higher than 40 mg
In the figure above, you are given the value of a start equal to 10 and the clover equal to 5. You are given a pole with three strings divided equally, the center string is tied to a wall and the two other strings carry either of the items. The first string has two stars and one clover which will have a total of 25 and the other string has one star and three clovers which will have a total of 25. The name of this type of problem is addition. Overall, the total weight of the items is 50.

Answer:
It will be $7602.3
Step-by-step explanation:
The equation 
gives the purchasing power of $10000 after x years.
Therefore, the sum of money $10000 will value 
after x number of years.
Now, after 9 years i.e. x = 9 years, the sum value of $10000 will become 
dollars. ( Answer )
