If the basic measuring unit in base-7 is 49 circles, what does the measuring unit of size .001seven look like
1 answer:
The measuring unit is the standard unit of a quantity
The measuring unit of size 0.001 is represented by one millionth circle
<h3>How to determine the unit of base 0.001</h3>The basic measuring unit in base 7 is given as:
49 circles
The above can be represented as:
Base 7 = 49 circles
Represent the base with n.
So, we have the following rule
For measuring unit 0.001, we have:
Evaluate the square
This means that,
The measuring unit of size 0.001 is represented by one millionth circle

Answer:
We conclude that the mean waiting time is less than 10 minutes.
Step-by-step explanation:
We are given that a public bus company official claims that the mean waiting time for bus number 14 during peak hours is less than 10 minutes.
Karen took bus number 14 during peak hours on 18 different occasions. Her mean waiting time was 7.8 minutes with a standard deviation of 2.5 minutes.
Let = <u><em>mean waiting time for bus number 14.</em></u>
So, Null Hypothesis, :
10 minutes {means that the mean waiting time is more than or equal to 10 minutes}
Alternate Hypothesis, :
< 10 minutes {means that the mean waiting time is less than 10 minutes}
The test statistics that would be used here <u>One-sample t test statistics</u> as we don't know about the population standard deviation;
T.S. = ~
where, = sample mean waiting time = 7.8 minutes
s = sample standard deviation = 2.5 minutes
n = sample of different occasions = 18
So, <u><em>test statistics</em></u> = ~
= -3.734
The value of t test statistics is -3.734.
Now, at 0.01 significance level the t table gives critical value of -2.567 for left-tailed test.
Since our test statistic is less than the critical value of t as -3.734 < -2.567, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region due to which <u>we reject our null hypothesis</u>.
Therefore, we conclude that the mean waiting time is less than 10 minutes.
