Answer:
c, i and 3
Step-by-step explanation:
if you look at the congruence signs, then you will see that the 70 degree angle is in the same place.
Answer: 5.76
Step-by-step explanation:
0.09 x 64 implies 0.09 in 64 places
To solve this, Multiply 0.09 x 64
It gives 5.76

Step-by-step explanation:
a. The point estimate is the mean, 47 days.
b. The margin of error is the critical value times the standard error.
At 31 degrees of freedom and 98% confidence, t = 2.453.
The margin of error is therefore:
MoE = 2.453 × 10.2 / √32
MoE = 4.42
c. The confidence interval is:
CI = 47 ± 4.42
CI = (42.58, 51.42)
d. We can conclude with 98% confidence that the true mean is between 42.58 days and 51.42 days.
e. We can reduce the margin of error by either increasing the sample size, or using a lower confidence level.
