If you would like to transform 50 cm to feet, you can do this using the following steps:
1 inch = 2.54 centimeters
1 inch ... 2.54 cm
x inches = ? ... 50 cm
1 * 50 = 2.54 * x
50 = 2.54 * x
x = 50 / 2.54
x = 19.69 inches
1 foot = 12 inches
1 foot ... 12 inches
y feet = ? ... 19.69 inches
1 * 19.69 = 12 * y
19.69 = 12 * y
y = 19.69 / 12
y = 1.64 feet
The correct result would be 1.64 feet.
The answer is A. k/6 + 8 - 2/k
So, 5 + 195 = 200.
800 × 56 = 44,800.

Answer:
A)
Note that
Lower Bound = X - z(alpha/2) * s / sqrt(n)
Upper Bound = X + z(alpha/2) * s / sqrt(n)
where
alpha/2 = (1 - confidence level)/2 = 0.025
X = sample mean = 1723.4
z(alpha/2) = critical z for the confidence interval = 1.959963985
s = sample standard deviation = 89.55083319
n = sample size = 30
Thus,
Lower bound = 1691.355235
Upper bound = 1755.444765
Thus, the confidence interval is
( 1691.355235 , 1755.444765 ) [ANSWER]

b)
We assumed taht the distirbution of these observations is approximately normally distributed.

c)
Yes, because the values are not far away from each other.
