Answer:
d. 0.133
Step-by-step explanation:
-Standard error is calculated using the formula:

#We substitute the given values in the formula to solve for E:

Hence, the standard error is 0.133 and the correct option is d
Answer:
exact form - b = -11/5
decimal form - b = -2.2
Mixed number form - b = -2 1/5
Answer:
(0.5848 ; 0.6552)
We are confident that about 58% to 66% of sea foods in the country are Mislabelled.
No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.
Step-by-step explanation:
Sample size, n = 51
p = 0.62
1 - p = 1 - 0.62 = 0.38
n = 515
Confidence level = 90% = Zcritical at 90% = 1.645
Confidence interval = (p ± margin of error)
Margin of Error = Zcritical * sqrt[(p(1-p))/n]
Margin of Error = 1.645 * sqrt[(0.62(0.38))/515]
Margin of Error = 1.645 * 0.0214
Margin of Error = 0.035203
Lower boundary = (0.62 - 0.035203) = 0.584797
Upper boundary = (0.62 + 0.035203) = 0.655203
(0.5848 ; 0.6552)
We are confident that about 58% to 66% of sea foods in the country are Mislabelled.
No, criticism isnt valid and generalization can be made once the assumptions for constructing a confidence interval is met.
Answer:
We get the final answer of -4x + 6
Step-by-step explanation:
Let's simplify step-by-step.
2x −3(2x−2)
Distribute:
= 2x+ (−3)(2x) + (−3)(−2)
= 2x+ −6x + 6
Combine Like Terms:
= 2x + −6x + 6
= (2x + −6x) + (6)
= -4x + 6
Answer:
17
Step-by-step explanation:
4(3) + 5 = ?
12 + 5 = 17
