Answer:
<h2>The answer is 0.008789.</h2>Step-by-step explanation:
The probability of getting a head or tail in a toss is .
It is given that in the 6th toss, the outcome should be head.
Rather than the 6th toss, there are 9 tosses. From these 9 tosses 1 toss can be selected in 9 ways.
Hence, the probability is = 0.008789.
Answer:
The confidence interval is
Step-by-step explanation:
We have given,
The Z interval (23.305,25.075)
Mean
Sample n=30
To find : The confidence interval?
Solution :
We know, The confidence interval is in the format of
E denotes the margin of error,
Where, U is the upper limit U=25.075
L is the lower limit L=23.305
Substitute the value of E and in the formula,
Therefore, The confidence interval is
