Answer:
The test statistic (z-score) of this one-mean hypothesis test is z=1.823.
Step-by-step explanation:
The null and alternative hypothesis are:
The significance level is 0.05.
The sample size is n=22.
The sample mean is M=157.
The standard deviation is 18.
The z-score can be calculated as:
The test statistic (z-score) of this one-mean hypothesis test is z=1.823.
Y - 5 = 3 - 9(y + 2)
Expand the brackets
y - 5 = 3 - 9y + 18
Move y to one side, and constants to the other
10y = 26
Solve for y
y = (26 / 10) = 2.6
Complete question :
Taylor earns $5 each time she walks her neighbor's dog. She has already earned $25. Write and solve an equation to find out how many more times Taylor needs to walk the dog to earn enough to buy a bike that costs $83.
Answer:
12
Step-by-step explanation:
Amount earned for walking dog = $5 per walk
Amount already earned = $25
How many more times dog needs to be walked to buy a bike which costs $83
Target amount = 83
(Target amount - already earned amount) / amount earned per Walk
(83 - 25) / 5
58 / 5
= 11.6
Hence, Taylor needs to walk her neighbor's dog 12 more times
