Answer:
17.1≤x≤23.1
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = x ± z*s/√n
x is the mean yield = 20.1
z is the 80% z-score = 1.282
s is the standard deviation = 7.66
n is the sample size = 11
Substitute
CI = 20.1 ± 1.282*7.66/√11
CI = 20.1 ± 1.282*7.66/3.3166
CI = 20.1 ± 1.282*2.3095
CI = 20.1 ±2.9609
CI = (20.1-2.9609, 20.1+2.9609)
CI = (17.139, 23.0609)
hence the required confidence interval to 1dp is 17.1≤x≤23.1
Just divide the two
1780/60=29.66 round to 30
Hope this helps have a nice nite
Hello!
45 + 10 + 6 = 61

Answer: $240.83
explanation:
Since he pays health insurance MONTHLY, you multiply 175x12=1200.
Since the others are yearly, just add those too 1,200.
1200+595+195=2,890.
Since you are looking for his monthly total you want to divide 2,890 by 12. Giving you the answer $240.83
