Answer:
The degrees of freedom are given by:
The p value for this case would be given by:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes
Step-by-step explanation:
Information given
represent the sample size
represent the confidence level
represent the sample variance
represent the value that we want to verify
System of hypothesis
We want to test if the true deviation for this case is lesss than 5minutes, so the system of hypothesis would be:
Null Hypothesis: 
Alternative hypothesis: 
The statistic is given by:
And replacing we got:
The degrees of freedom are given by:
The p value for this case would be given by:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true deviation is not ignificantly lower than 5 minutes

I did it in a on a piece of paper
<h2>
Probability that the second marble will be blue is 0.44</h2>
Step-by-step explanation:
There are 10 marbles in a bag. 3 are red, 4 are blue, 2 are green, and 1 is yellow.
Total number of marbles = 10
Given that first marble is yellow.
New total number of marbles = 10 - 1 = 9
Now we have 3 are red, 4 are blue, 2 are green.
Number of blue marbles = 4
We need to find drawing probability of blue marble from 9 marbles.
Let the probability be, p
Probability that the second marble will be blue is 0.44
Answer:
95⁰
Step-by-step explanation:
next time you want to figure this out, here's how
- they are supplementary angles, so you just subtract 45⁰ from 180⁰
180-45=95
so, you would get the answer 95⁰
for next time, you might not have as much information as you do in this equation so be careful
hope this helps!
