Answer:
The answer is below
Step-by-step explanation:
From the table, the mean (μ) = 1390.75 and the standard deviation (σ) = 518.75
The confidence level (C) = 90% = 0.9
α = 1 - C = 1 - 0.9 = 0.1
α/2 = 0.1 / 2 = 0.05
The z score of α/2 (0.05) is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.645.
The margin of error (E) is given as:
The confidence interval = μ ± E = 1390.75 ± 228.07 = (1162.68, 1618.82)
The confidence interval is between 1162.68 and 1618.82.
Answer:
it will take her minutes more to walk down to Raj's House
Step-by-step explanation:
It took Sheldon minutes to walk to Raj's house
It also took Sheldon minutes to use the bus.
To get the time difference between the two transport mechanisms, we subtract their different time durations.
This will be
We can convert this to Mixed fractions as shown minutes.
Therefore, it will take her minutes more to walk down to Raj's House
