Let the following sample of 8 observations be drawn from a normal population with unknown mean and standard deviation: 22, 18, 1
BigorU [14]

Answer:

a:  Sample mean: 20, Sample standard deviation: 1.732

b:  19.13 <µ < 20.87

c:  18.84< µ < 21.16

d:  as the confidence level increases, the interval becomes wider

Step-by-step explanation:

a:  Sample mean is found by adding up all the individual values of the sample, then dividing by the total number of values in the sample.  

Sample standard deviation is the square root of the variance

See the first attached photo for the calculations of these values.

We need to create a 80% confidence interval for the population.  Since n < 30, we will use a t-value with degree of freedom of 7 (the degree of freedom is always one less than the sample size.  

Look for the column on the t-distribution chart that has "area in two tails" of 0.20 (80%), and row 7 (degree of freedom)

The t-value is 1.415

See the second attached photo for the construction of the confidence interval

We need to create a 90% confidence interval for the population.  Since n < 30, we will use a t-value with degree of freedom of 7 (the degree of freedom is always one less than the sample size.  

Look for the column on the t-distribution chart that has "area in two tails" of 0.10 (90%), and row 7 (degree of freedom)

The t-value is 1.895

See the third attached photo for the construction of the confidence interval

Ben is paid £8.50 per hour.
skelet666 [1.2K]

Answer:

£103.70

Step-by-step explanation:

Payment per hour = £8.50

Overtime payment = 1.4 × 8.50

= £11.90

Ben worked for 11 hours.

Normal time = 8 hours

Overtime = 3 hours

Total earnings = (8 hours × 8.50) + (3 hours × 11.90)

= £68 + £35.7

= £103.70

Ben earned £103.70 for working for 11 hours

A wedding ring is dropped from a tall building, the distance it has fallen in feet is given by 16t^2, where t is the time in sec
natka813 [3]

Answer:

64

Step-by-step explanation:

As given, the diatance at any point after t seconds is given by

s(t)=16t²

At t=2 seconds then

s(2)=16*2²=16*4=64

Since we're not given the units, it may be feet, inches, meters, kilometers, miles etc. Therefore, the diatance is equal to 64 units
