75% is equal to 75/100, which can be reduced to 3/4. So it's 3/4 * 80 = 60
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.
Answer:
It would be 2.17391304348 but you can round it to the nearest tenths or hundreths, whatever you choose
Step-by-step explanation:
If you want to round it to the nearest tenths, then it would be 2.2
If you want to round it to the nearest hundreths, it would be 2.17

Answer:
Step-by-step explanation:
The answer could be:
1400x = xt
Where 1400 = the initial altitude
Where t = time ( per minute)
And where x equals a certain number.
5_3 ; x 1
<em>5 = 3x </em>
<u>x = 5/3 </u>
