Answer:
Assignments finished = 7
Step-by-step explanation:
Given that:
Time taken for one assignment = 20 minutes
Time spent on working = 2 hours 20 minutes
2 hours = 120 minutes
Time spent on working = 120 + 20 = 140 minutes
Number of assignments =
Number of assignments =
Number of assignments = 7
Hence,
Assignments finished = 7
Answer:
From the given options we can say the correct answer is d.) 6.3
Step-by-step explanation:
The waiting times at the bank are given to be normally distributed.
The mean of the waiting time is given as = 3.7 minutes
The given standard deviation is = 1.4 minutes
It is required to find the waiting time at the 97th percentile.
So we are required to find the time which can be said to be the waiting time which occurs with 97 % probability.
Let the time required be designated as y.
Therefore we can write p(X < y) = 0.97 (where 0.97 means the 97th percentile)
This is a left tailed test.
Using the formula from MSEXCEL to find y we get
y = NORMINV(0.97, 3.7, 1.4) = 6.333.
The other approach would to find the Z value corresponding to the probability value from the Z Table
The Z value for a probability of 0.97 gives us Z = 1.881 .
Therefore . Therefore y = (1.881 × 1.4) + 3.7 = 6.33
Therefore from the given options we can say the correct answer is d.) 6.3
