Answer: 1.467
Step-by-step explanation:
Formula of Margin of Error for (n<30):-
Given : Sample size : n= 22
Level of confidence = 0.90
Significance level : 
By using the t-distribution table ,
Critical value : 
Standard deviation: 
Then, we have
Hence, the margin of error for the confidence interval for the population mean with a 90% confidence level =1.467
Answer:
1144.18 e-12 chips
Step-by-step explanation:
Conversation rate of nanometers
1 nanometers =1* 10^-12 km
35 nanometers= 35 *10^-12
Radius of earth= 6371 km
Circumference of earth = 2πr
Circumference= 2*22/7*6371
Circumference=40046.29 km
The number of chips to be used to circle the earth
= 40046.29/35 *10^-12
=1144.18 *10^-12
= 1144.18 e-12 chips
The ration is 12 muffins to every 21 donuts
The answer is (-2, -3) since 2*-2–(+)3= -1 and 2*-2-4*-3= 8.
