Answer:
$4.911 million or $6.481 million
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.
Step-by-step explanation:
Given that:
sample size n = 18
standard deviation σ = 1.70
confidence interval = 95%
Sample mean
5.696
The level of significance = 1 - C.I
= 1 - 0.95
= 0.05
The critical value of from the Z tables
The 95% C.I for the mean is;
= 5.696 ± 0.785372
= (5.696 - 0.785372 , 5.696 + 0.785372 )
= ( 4.910628 , 6.481372 )
≅ $4.911 million or $6.481 million.
Thus, we are 95% confident that the mean amount of all venture-capital investments in the high-tech industry is somewhere between $4.911 million and $6.481 million.

Answer:
The value of φ(n) is 6720, while the value of d is 6413 and the Encrypted message is C=3984 while the decrypted one is M=8720.
Step-by-step explanation:
p is given as 71
q is given as 97
so n is
Now the φ(n) is given as
So the value of φ(n) is 6720.
Now
As e is 197 so
The value of d is 6413.
m=8720 so the Encryption is given as
Now the decryption is
So the Encrypted message is C=3984 while the decrypted one is M=8720.
