2.6 A recent article in a college newspaper stated that college students get an average of 5.5 hrs of sleep each night. A student who was skeptical about this value decided to conduct a survey by randomly sampling 25 students. On average, the sampled students slept 6.25 hours per night. Identify which value represents the sample mean and which value represents the claimed population mean.

Mean of the Population or The claimed population mean 'μ' = 5.5 hrs.

Mean of the sample 'x⁻' = 6.25 hours

Step-by-step explanation:

Explanation:-

Given data A recent article in a college newspaper stated that college students get an average of 5.5 hrs. of sleep each night

Discuss about total college students so

Mean of the Population 'μ' = 5.5 hrs.

Given random sample size 'n =25

Given data the sampled students slept 6.25 hours per night

mean of the sample 'x⁻' = 6.25 hours

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
