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.
I think answer should be 10 Please give me brainlest I hope this helps let me know if it’s correct thanks
<span>A gallon of water weighs 8 1/3 lb
</span><span>1 1/5 gallon....................? lbs
</span>8 1/3 * 1 1/5
= 25/3 * 6/5
= 10
answer : <span>1 1/5 gallon of water weighs 10 lbs</span>
I think it’s m^5 because if you multiply m^7 times m^2 you get m^14 and if you combine it with m^9 you subtract 9 and get m^5
Answer:400. 10^2 x 12/3 = 400.
