Answer:
B) 1.622 to 1.778 includes the mean of the population beta.
Step-by-step explanation:
We have the standard deviation for the sample, so the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom,which is the sample size subtracted by 1. So
df = 100 - 1 = 99
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 99 degrees of freedom(y-axis) and a confidence level of
. So we have T = 1.9842
The margin of error is:
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 1.7 - 0.078 = 1.622.
The upper end of the interval is the sample mean added to M. So it is 1.7 + 0.078 = 1.778.
Thus the correct answer is given by option B.
Answer:
Q1A) $1750
Q1B) 64.3 %
Q2A) $49.50
Q2B) 66%
Step-by-step explanation:
Q1A) Total prize money for competition
= $500/4 × 14
= <u>$</u><u>1</u><u>7</u><u>5</u><u>0</u>
Q1B) Percentage of money given as first prize
= 9/14 × 100%
= <u>6</u><u>4</u><u>.</u><u>3</u><u> </u><u>%</u> (3 s.f)
Q2A) Total amount spent on music, films and books
= $16.50/5 × 15
= <u>$</u><u>4</u><u>9</u><u>.</u><u>5</u><u>0</u>
Q2B) Total amount as a percentage of $75
= 49.5/75 × 100%
= <u>6</u><u>6</u><u>%</u>
6.4−2.4÷0.1
According to PEMDAS
divide comes first in this problem
2.4 /.1 =24
6.4 - 24
-17.6
