Answer:
With 95% confidence when n equals 44, the population mean is between a lower limit of 33.96 and an upper limit of 40.04
Step-by-step explanation:
Confidence Interval = mean + or - Error margin (E)
mean = 37
sd = 10
n = 44
degree of freedom = n - 1 = 44 - 1 = 43
t-value corresponding to 43 degrees of freedom and 95% confidence level is 2.0165
E = t × sd/√n = 2.0165×10/√44 = 3.04
Lower limit = mean - E = 37 - 3.04 = 33.96
Upper limit = mean + E = 37 + 3.04 = 40.04
95% confidence interval is between 33.96 and 40.04

Answer: What's the exponents?
Step-by-step explanation:
5.2+3.01=8.21
but then there's no exponents that you stated. So it would be 8.21x10^?
If the tens do have exponents above them, add them together.

Answer:
£25185
Step-by-step explanation:
It depends on how many days are in your year. If it's a regular year, it's 365 days. If it's a leap year 366 days.
69 x 365 = 25185
69 x 366 = 25254
The answer would be three
