The total distance traveled in 2-hour time is 50 miles. (option g)
Shauna drove 75 miles in 3 hours at a constant speed, so the total distance covered in 3 hours is 75 miles to find the distance covered in 2 hours, we first need to find the distance or miles covered in 1 hour
To find the distance Shauna traveled in 2 hours, use the following formula: –
Speed = distance/time
Total distance traveled = 75 miles
Total time = 3 hours = 3 hours
Speed = 75/3
Speed = 25 miles per hour
Distance traveled in 2-hour time is 50 miles.

<span>The constant rate of change is 30 seconds because:
1 mile=30 seconds
2 miles=1 minute
3 miles=1 minute and 30 seconds
4 miles=2 minutes
5 miles=2 minutes and 30 seconds
or in other words 2.5</span>
Answer & Step-by-step explanation:
Null hypothesis (H0): μ=100 lbs
Alternative hypothesis (H1): μ>100 lbs
<em>We must use the t-student distribution because the population standard deviation is unknown.</em>
t-statistic formula:
t= (xbar-m)/(S/(sqrt(n)))
xbar: sample mean
m: hypothesized value
S: sample standard deviation
n: number of observations
t=(104-100)/(10/sqrt(25))
t-statistic= 2
The critical value from the t-student distribution with, 25-1 degrees of freedom and 1% significance level , is 2.4922
Because the t-statistic is less than the critical value, then you do not reject the null hypothesis. Then there is NO statistical evidence to affirm that the average weight population of product X is greater than 100 lbs.
