First, we establish
our hypothesis:
<span>Null hypothesis H0: μ = $1.00 </span>
Alternative hypothesis
Ha: μ ≠ $1.00
<span>Let’s say X = the sample average cost of a daily newspaper
= 0.96</span>
u = population mean
cost = 1.00
S = sample standard
deviation = 0.18
Calculating for z
value:
z = (X – u) / S
z = (0.96 – 1) / 0.18
z = – 0.222
From the standard
distribution table at this z value, p-value = 0.4129
Since alpha = 0.01,
the decision therefore is:
<span>Do not reject the null
hypothesis because the p-value is greater than 0.01. There is enough evidence
to support the claim that the mean cost of newspapers is $1. </span>
Answer:
1/5? 0.2?
Step-by-step explanation:
Answer:
nicce
Step-by-step explanation:
Answer:
he rose by 71 feet and it took him 6.88 mins to do so.
Step-by-step explanation:
So we know that the diver is going up in elevation cause he is ascending and he ascended 71 ft. Along with the fact that the total dive was 20 1/8 mins with roughly converts to 20.13 mins and if we take that number and subtract the amount of time he stayed at the elevation of 71ft we know that it took him 6.88 min to rise to the elevation of -18.9.
