Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
H0: µ = 5000
For the alternative hypothesis,
H1: µ > 5000
Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = population standard deviation
n = number of samples
From the information given,
µ = 5000
x = 5430
σ = 600
n = 40
z = (5430 - 5000)/(600/√40) = 4.53
Looking at the normal distribution table, the probability corresponding to the z score is < 0.0001
Since alpha, 0.05 > than the p value, then we would reject the null hypothesis. Therefore, at a 5% level of significance, it can be concluded that they walked more than the mean number of 5000 steps per day.
The answer is 64!!

Answer:
2,095,426.517
Step-by-step explanation:
From the question above we are required to find the product of 698475.50585057 and 3
Therefore the product can be calculated as follows
698475.50585057 × 3
= 2,095,426.517
Hence 698475.50585057 multiplied by 3 is 2,095,426.517
Answer:
32
Step-by-step explanation:
39 = 4(x + 5) + 2x + 1
39 = 4x + 20 + 2x + 1
39 = 6x + 21
18 = 6x
x = 3
MN = 4(x + 5)
MN = 4(3 + 5)
MN = 4(8)
MN = 32
hope this helped!
