Answer:
C
Step-by-step explanation:
x axis is the horizontal line, so count positive 6, not negative, from there. Then go 3 upwards since its positive 3 :)
Answer:
(A) With 99% confidence, the proportion that favours the Green initiative is between 418.895 and 423.105 (no approximation; answers were gotten exactly in 3 decimal places).
(B) If many groups of 593 (greater than the initial sample size of 556) randomly selected Americans were surveyed then a different confidence interval would be used or produced from each group.
About 90% of these confidence intervals will contain the true population proportion of Americans who favour the Green initiative and about 10% will not contain the true population proportion.
Step-by-step explanation:
(A) 99% of 421 = 416.79
421 - 416.79 = 4.21
4.21 ÷ 2 = 2.105
(421-2.105), (421+2.105)
The lower and upper limits are:
[418.895 , 423.105]
(B) A wider confidence interval such as 90% will be better suited in a case of multiple samples like this.
The positions/jobs are different. One person can not take two jobs so the number of total candidates decreases by one for each position..
Manager = 15 candidates
Associate Manager = 14 candidates
Assistant Manaager = 13 candidates
15 × 14 × 13 = 2730 possible outcomes

The answer is B
They all have a same CENTER.
ALL HAVE A
DIFFERENT RADIUS, Hence all will obviously have a different
DIAMETER
