Answer: (0.42648,0.47352)
It means the interval (0.42648,0.47352) that we can be 95% sure contains the population proportion.
Step-by-step explanation:
Given : The proportion of U.S. adult report that they live with one or more chronic conditions :
Standard error :
Significance level :
Critical value :
The confidence interval for population proportion is given by :-
Hence, a 95% confidence interval for the proportion of U.S. adults who live with one or more chronic conditions =(0.42648,0.47352)
It means the interval (0.42648,0.47352) that we can be 95% sure contains the population proportion.
Answer:
See below
Step-by-step explanation:
a)
<u>Day 1</u>
- 70 min for 10 km
- Rate = 70/10 = 7 min/km
<u>Day 10</u>
- 2h40 min for 20 km
- 2*60+40 = 160 min for 20 km
- Rate = 160/20 = 8 min/km
<u>Day 20</u>
- 4 h 15 min for 30 km
- 4*60 + 15 = 255 min for 30 km
- Rate = 255/30 = 8.5 min / km
b)
<u>From the rate change we see:</u>
- 1 min increase when the distance increases from 10 km to 20 km
- 0.5 min increase when distance increases from 20 km to 30 km
So we see 1 min increase per twice the distance increase
- With the same rate increase we can expect 1 min increase from 20 km to 40 km, which gives us the rate of 9 min/km
- With same logic we get 9.055 km/min rate for 44 km distance
<u>Total time it takes:</u>
- 9.055*44 = 398.42 min = 398.42*1/60 min = 6 h and 38.42 min
You can do 1/24; 3/24; 5/24 in that order

Answer:
t = 12
Step-by-step explanation:
12/4 + 12 = 15
3 + 12 = 15
15 = 15
t = 15
