They making me type 20 things but ima day its 72 cuh
Answer:
On Monday the value was 1.448, Tuesday it was 1.443, Wednesday it was 1.452, and Thursday it was 1.458.
Step-by-step explanation:
a repeating decimal is placed over 9's instead of 0's. for example: 0.23 = 
, but 0.232323... = 
a) x = 0.121212
b) 100(x) = 100(0.121212)
100x = 12.1212
c) 100x = 12.1212
- <u> x = 0.1212</u>
99x = 12
x = 
d) -2 <em>= -2
when simplified</em>
The number is rational becase it has a repeating decimal
Given:
n = 20, sample size
xbar = 17.5, sample mean
s = 3.8, sample standard deiation
99% confidence interval
The degrees of freedom is
df = n-1 = 19
We do not know the population standard deviation, so we should determine t* that corresponds to df = 19.
From a one-tailed distribution, 99% CI means using a p-value of 0.005.
Obtain
t* = 2.8609.
The 99% confidence interval is
xbar +/- t*(s/√n)
t*(s/√n) = 2.8609*(3.8/√20) = 2.4309
The 99% confidence interval is
(17.5 - 2.4309, 17.5 + 2.4309) = (15.069, 19.931)
Answer: The 99% confidence interval is (15.07, 19.93)
Answer:
For the first question, the answer is 4/3. For the second it is 16.
