Answer:
<h2>
$5.03</h2>
Step-by-step explanation:
 
Given data          
Sample Mean (M):  $48.77  
Sample Size (n): 20
Standard Deviation (σ) :  $17.58
Confidence Level: 80%
  we know that z*-Values for 80% Confidence  Levels is 1.28
 the expression for margin of error is given bellow\
MOE= z*σ/√n
 We can now substitute into the expression and solve for the MOE as 
MOE= 1.28*17.58/√20
MOE= 22.502/4.47
MOE= 22.502/4.47
MOE= 5.03
The margin of error for a 80 % confidence interval is $5.03
 
        
             
        
        
        
Answer: The probability that the number made up of the first two digits on the clock is less than 25 is 1. 
Step-by-step explanation:
The probability of an event is a number which describe the chances of the event will happen. 
We know that on digital clock, the first two digits always show as number less that 25.
Therefore, the event that the number made up of the first two digits on the clock is less than 25 is certain.  [Since An event that is certain to happen has a probability of 1.]
Hence, the probability that the number made up of the first two digits on the clock is less than 25 is 1.
