The answer is the 2nd option of 60 degrees.
Answer:
The probability it is greater than or equal to 0.95 and less than or equal to 0.96
Step-by-step explanation:
In order to calculate the probability that weekly demand exceeds 4,044 we would have to calculate the z value as follows:
Z= (X-mean)/standard deviation
Z= (4044 - 3211)/484
Z=1.721
So, looking for standard normal distribution table 1.7 from row, we get values from 0.9554 till 0.9633, for column 0.02 it is 0.9573
Therefore, the probability it is greater than or equal to 0.95 and less than or equal to 0.96
Here ,300 people present in library are asked to choose their favourite book and we have to tell how many choosed mystery as their favourite book ?
Before solving these type of questions , have a look on the pie chart , from their we got that , 16% of 300 have choosed mystery as their favourite book.
Now , 16% of 300 = (16/100)×300 = 16×3 = 48
So , 48 people choosed mystery as their Favourite book .
Hence , Option C) 48 is correct
