Step-by-step explanation:
8 players were on the team last year
To solve for the confidence interval for the true average
percentage elongation, we use the z statistic. The formula for confidence
interval is given as:
Confidence interval = x ± z σ / sqrt (n)
where,
x = the sample mean = 8.63
σ = sample standard deviation = 0.79
n = number of samples = 56
From the standard distribution tables, the value of z at
95% confidence interval is:
z = 1.96
Therefore substituting the known values into the
equation:
Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)
Confidence interval = 8.63 ± 0.207
Confidence interval = 8.42, 8.84

Answer:
Step-by-step explanation:
1 km= 1000m
1.5 km = 1 x 1000 + 500
1000 + 500
1500m
1500 m : 250 m
750 m : 125 m
150 m : 25 m
30 m : 5 m
6 m : 1m
0.0
