All except 0. The inequality is saying that x must be less than or equal to 3 which all answers except 0 are.
A 95% confidence interval on the z-table is 1.96.
Now find the standard error using the formula: standard deviation / square root sample size:
0.7 / √100 = 0.07
Multiply to the confidence interval: 1.96 x 0.07 = 0.137 = 0.14
Now add and subtract tot he average weight:
14 - 0.14 = 13.86
14 + 0.14 = 14.14
The answer is 13.96 ≤ u ≤ 14.14
7×4=28+32=60+3 this is a bit long

Answer: They have to sell 21 t-shirts to reach their goal.
T-shirt: $5
Goal: $150
$45 has been raised so far (that means they sold 9 T-shirts) 5 x 9 = $45
150/5 = 30 t-shirts (they need to sell 30 t-shirts in the total)
150-45 = They need $105 to archive their goal
105/5 = 21 t-shirts
