Answer:
9+1 = 10, 9+4 is not correct because it does not equal 10.
Step-by-step explanation:
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: its <
Step-by-step explanation:
2 is the answer
That’s the answer.
Answer:
average of the two observations in the center of the data array
Step-by-step explanation:
When there is an odd number, we use the middle
Example
1,5,9
The median is 5
When there is an even number
1,3,5,7
The middle is between the 3 and 5 so we average the middle number
(3+5)/2 = 4
