A local weather enthusiast wants to see if the last five summers have been warmer than normal for Eloy, Arizona. From the Nation

Answer:

Step-by-step explanation:

This is a question on hypothesis testing.

Population mean based on 30 year average for July was 90 with

a std deviation of 2.1

Sample of 5 shows average 93.5

To check whether sample average = population average

H0: x bar =90

Ha: x bar not equal 90(Two tailed test)

Test statistic = $\frac{93.5-90}{\frac{2.1}{\sqrt{5} } }$

=3.73

Since this lies outside the range (-1.96, 1.96) we reject null hypothesis

Hence we cannot say sample mean equals 90

What is the value of x

barxatty [35]

X = 15

X + 90 = 7x

X = 7x - 90

X - 7x = -90

-6x = 90

Divide both sides by -6

X = 15
