Suppose a shoe store wants to determine the current percentage of customers who are males. how many customers should the company survey in order to be 90% confident that the estimated (sample) proportion is within 3 percentage points of the true population proportion of customers who are males?

1067

Step-by-step explanation:

Given : Level of confidence = 0.90

Significance level :

By using the normal distribution table,

Critical value :

Margin of error :

The formula to find the population proportion if prior proportion of population is unknown  :-

Hence, the company should survey minimum sample having size  =1067

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
