This investment seems very diverse. It is divided into 5 different categories with no more than 25% in any one category.
It is a very conservative approach. 95% of the investments are in very stable account. Only 5% is devoted to a developing firm.
This investment plan would be for an investor who is very fearful of losing money. They would most likely be close to retirement age, in a situation where they just want to maintain the value of their account.
Answer:
Reject H0; there is significant evidence that the proportion of site users who get their world news on this site has changed since 2013 and is significantly different from 45%
Step-by-step explanation:
Sample size, n = 3603
x = 1697
Phat = x/n = 1697/3603 = 0.4709 =47.09%
H0 : p = 0.45
H1 : p > 0.45
The test statistic :
(phat - p) / sqrt[(p(1 - p)) /n]
(0.4709 - 0.45) / sqrt[(0.45(0.55))/3603]
0.0209 / 0.00828810932
Test statistic = 2.5217
The Pvalue :
Using the Pvalue from Test statistic calculator ; α = 0.05 ;
Pvalue at 95% confidence = 0.005839
Pvalue < α ;
Hence, we reject the Null
Therefore, we conclude that the sample gives evidence that the proportion of site users who get their world news on this site has changed since 2013.
Answer:
14. B 9, Isosceles
15. Corresponding angles; alternate interior angles; verticle angles
Step-by-step explanation:
Question 14 explanation -
Because two of the triangle's angles are congruent, this triangle classifies as an Isosceles Triangle. Therefore, we know that sides AB and AC must be congruent. This makes it easy to solve for x...just set both side lengths equal to each other and solve.
mAB = mAC
16 = x + 7
16 - 7 = x + 7 - 7
9 = x
x = 9
