For the dot plot write down the numbers from 18 to 26 and then plot how ever many points there are of each value
A posted speed limit of 55 mph means that: You may drive 55 mph only under favorable conditions.
<h3>What is the speed limit?</h3>
Speed limits on road traffic, as used basically to set the legal maximum speed at which vehicles are permitted to utilize on a given stretch of road.
Now generally, speed limits are normally indicated on traffic signs reflecting the maximum allowable speed in kilometers per hour (km/h) or eevn miles per hour (mph). They are primarily set by the legislative bodies of national or provincial governments and then enforced by law enforcement agencies. This suggests that speed limits varies from road to road and is even absent in some certain areas.
Now, in this question we are told that the posted speed limit is 55 mph. Thus, from our definitions of speed limits above it is clear that A posted speed limit of 55 mph means that: You may drive 55 mph only under favorable conditions.

Answer:
If it's 107% of 50 the answer would be 53.5
If it's 107% more than 50 it would be 103.5
Step-by-step explanation:
107% of 50 is 53.5
50 × 107% = 53.5
50 × 107% = 53.5
+50
--------
103.5
Answer:
The p value for this case would be given with this probability:
For this case since the p value is higher than the significance level of 0.01 we have enough evidence to fail to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is significantly less than 25 min.
Step-by-step explanation:
Information given
represent the sample mean
represent the population deviation
sample size
represent the value to check
represent the significance level
z would represent the statistic
represent the p value
Hypotheis to test
We want to verify if the true mean is less than 25 min, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic would be given by:
(1)
And replacing the info given we got:
The p value for this case would be given with this probability:
For this case since the p value is higher than the significance level of 0.01 we have enough evidence to fail to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is significantly less than 25 min.
