Answer:
Pablo drove the greatest distance of 527 miles.
Missing Content:
Since information on Pablo is not given, it is impossible to solve this problem. Let us assume some scenario for Pablo. Say:
(3)Pablo averaged 52.7 miles per hour and drove for 10 hours.
Step-by-step explanation:
Using this information, we can find out the data on Al,
Al drove 1 hour longer than Pablo so,
Time Al drove= 10+1 =11 hours
Average rate of Al=Pablo's average rate-5= 52.7-5 = 47.7 miles per hour.
We know that,
Average Speed =
Distance =Average Speed x Time
Distance travelled by Al = 47.7 x 11 =524.7 miles
Distance Travelled by Marsha = 50 x 9=450 miles
Distance Travelled by Pablo= 52.7 x 10= 527 miles
<u>As we can see that Pablo drove the greatest distance which is 527 miles.</u>
Answer:
a. The mean is 4.5 and the standard deviation is 0.3818.
b. 4.5
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 4.5 and a standard deviation of 2.291.
This means that
a. Find the mean and the standard deviation of the resulting distribution of sample means for n=36.
By the Central Limit Theorem, the mean is 4.5 and the standard deviation is
The mean is 4.5 and the standard deviation is 0.3818.
b. The mean of the resulting distribution of the sample means is:________
By the Central Limit Theorem, 4.5.
