Answer:
0.025 is the standard error of mean.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 100
Sample mean = 13 psi
Population standard deviation = 0.25 psi
We have to find the standard error of the mean.
Formula:
Standard error =

0.025 is the standard error of mean.
All 12 months have 28 days in it.
because every month has 28 days ( February) or more number of days like the other months(Jan, Mar..)
Answer:
seventh interior angle=∠x=29°
Step-by-step explanation:
sum of interior angle of polygon is equal to 360°
let seventh angle of heptagon is x
∠x+47°+55°+62°+64°+54°+49°=360°
∠x=360°-(47°+55°+62°+64°+54°+49°)
∠x=360°-331°=29°
∠x=29°
seventh interior angle=∠x=29° answer
