Answer:

H0 : μ = 1220

H1 : μ > 1220

Test statistic = 1.30

Step-by-step explanation:

Sample mean, x = 1235.91

Standard deviation, σ = 211.67

Sample size, n = 300

The hypothesis :

Null ; H0 : μ = 1220

Alternative ; H1 : μ > 1220

Tbe test statistic :

(x - μ) ÷ (σ/√(n))

(1235.91 - 1220) ÷ (211.67/√(300))

15.91 / 12.220773

= 1.3018

= 1.30

1. Measures of CenterLions: 14, 13, 31, 21, 24, 19Jets scores: 15, 17, 13, 6, 26, 21Which team had a higher medianscore? By how
larisa86 [58]
Lions 
because if you find the median in both there will be two medians so that means you have to add up the two medians.

For the first one the medians were 31 and 21 so add 31+21=52 and 52/2=26

For the second one the medians were 13 and 6 so add 13+6=19 and 19/2=9.5 

So the higher score woud be lions and it would by higher by 16.5
hope this helped:)
