Heeelppp - T Test / Chi Square on my data please?

Hello, I am doing some work and need some help on statistics please (T testing / Chi Square). Maths is way not my strong point!

So I have collected some data and I want to test the significance if Apple Juice is better than Orange juice.

So my main aim is to find out what’s the best between Orange juice and Apple juice

My questions is as follows:
I have collected data at 4 different shops, 2 of the shops sell orange juice, 2 of the shops sell apple juice:

Shop A – Orange juice
Shop B - Orange juice
Shop C – Apple juice
Shop D – Apple juice

A Customer survey was also carried out to see proportion of customers who bought juice
Shop A – 71%
Shop B - 69%
Shop C – 52%
Shop D – 66%

For these 4 shops I have also collected data on the proportion of customers coming to the shops when it was closed
Shop A – 16%
Shop B - 13%
Shop C – 11%
Shop D – 12%

A traffic survey was carried out on the roads where the shops were located
Shop A – Average speed of vehicles was 31mph, 602 cars per hour
Shop B - Average speed of vehicles was 30mph, 551 cars per hour
Shop C – Average speed of vehicles was 32mph, 577 cars per hour
Shop D – Average speed of vehicles was 28mph, 300 cars per hour

I need to analyse the data collected to see if there is any statistical significance. Could this be carried out using t- testing or Chi Squared or any other method?

And if so would anyone be kind enough to show me step by step how I would do it using the data above. The STATS video tutorials just really aint sinking in,

Thanks
