Answer:
Step-by-step explanation:
Highest weight = 116 g
Lowest weight = 79 g
<h3><u>Range:</u></h3><h3>= Highest weight - lowest weight </h3>
= 116 g - 79 g
= 37
Step-by-step explanation:
If James wants to cover both of his children at his current salary until they both can support themselves on their own, he would need a 10-year term policy (if the youngest moves out when he/she is 21) with a face value of $500,000 (current salary-$50,000*10 years).
Subtraction of a negative is the same as addition.
-10 - (-2)
-10 + 2 = -8
Your answer is: -8
X actually equals the cube root of 6
Answer:
Margin of Error = 5.4088 ;
Confidence interval = (30.1 ; 40.9)
Interval estimate are almost the same
Step-by-step explanation:
Given that :
Population standard deviation, σ = 9.3
Sample size, n = 8
Xbar = 35.5
Confidence level = 90%
The confidence interval:
Xbar ± Margin of error
Margin of Error = Zcritical * σ/sqrt(n)
Zcritical at 90% = 1.645
Margin of Error = 1.645 * 9.3/sqrt(8) = 5.4088
Confidence interval :
Xbar ± Margin of error
35.5 ± 5.4088
Lower boundary = (35.5 - 5.4088) = 30.0912 = 30.1
Upper boundary = (35.5 + 5.4088) = 40.9088 = 40.9
(30.1 ; 40.9)
T distribution =. (30.5 ; 40.5)
Normal distribution = (30.1, 40.9)
