Answer:
Decimal form to nearest hundredth= 0.36
percent form to nearest tenth= 35.7%
Improper fraction= 11/30.8
Answer:
17
Step-by-step explanation:
15/(6 2/3)
First, change the mixed fraction into improper fraction.
6 2/3 = 20/3
15/(20/3)
Next, flip the second fraction to change the first division into a multiplication.
15 x (3/20)
Multiply 15 and 3 together.
15 x 3 = 45
Divide 45 with 20
45/20 = 2.25
0.25 = 25/100 = 1/4
2 1/4, or 2.25 is your answer
hope this helps
The 'part b' of this question is incomplete. I got the complete form of 'part b ' from google as below:
(b) Find a 90% confidence interval for the mean increase in production of interferon gamma after drinking tea for one week.
Answer:
a) The most appropriate method for this analysis is paired data difference in means (option A).
b) The 90% Confidence interval is 62.3 to 523.7.
Step-by-step explanation:
Given details:
Sample= 5
Mean difference: \bar{X_d}=293
Difference standard deviation: S_d=242
a) The most appropriate method for this analysis is paired data difference in means.
b) t value at 90%= 2.132
CI = dbar +/- t *(sd/sqrt(n))
= 293 +/- 2.132 *(242/sqrt(5))
= (62.3 ,523.7)
The 90% Confidence interval is 62.3 to 523.7
