Answer:
261.71
Step-by-step explanation:
The calculation of days is shown below:-
where,
Mean = 270
standard deviation is 8
And, the normsinv is -1.036
Now placing these values to the above formula
So, the number of days is
= 270 + (-1.036433389) × 8
= 270 + (-8.29146711)
= 261.708533
or
= 261.71
Therefore for computing the number of days we simply applied the above formula and for (-1.036433389) please find in the attachment.

Answer:
t = d/S
Step-by-step explanation:
S = d/t
Cross multiply
S x t = d
Divide both sides by S
S/S x t = d/S
t = d/S
