a chemist for a paint company conducted an experiment to investigate whether a new outdoor paint will last longer than the older

paint. fifty blocks made from the same wood were randomly assigned to be painted with either the new paint or the old paint. the blocks were placed into a weather-controlled room that simulated extreme weather conditions such as ice, temperature, wind, and sleet. after one month in the room, the blocks were removed, and each block was rated on texture, shine, brightness of color, and chipping. the results showed that the blocks painted with the new paint generally had higher ratings than the blocks painted with the old paint. however, an analysis of the results found that the difference in ratings was not statistically significant. what can be concluded from the experiment?

Q : Describe the sights and sounds of a crowded shopping mall.
yanalaym [24]
It was a sweltering Saturday afternoon, just the perfect weather to seek refuge in the air-conditioned neighbourhood shopping mall just a stone's throw away from my home. As I entered the shopping mall, Jurong Point , the cold air swept across my face, leaving a refreshing sensation.
The scene that greeted me was that the place was bustling with activities. Many parents were tagging their small children along with them and pushing strollers with young babies fallen asleep peacefully inside. There were also a few couples who strolled hand in hand lovingly, looking around casually for suitable clothes to try. The place was crammed like sardines and there was hardly any space to move. Sometimes the customers' skin even brushed against each other!
I then proceeded to the second floor via the escalator after scanning the crowd briefly. Over at the second floor, it was relatively less crowded as it was the typical lunch hour, so the customers were enjoying their lunch in the restaurants. There was a famous supermarket named Cold Storage, Popular bookshop and Golden Village cinema just to name a few shops. Additionally, there was a variety of restaurants to choose from- ranging from local delicacies to popular Korean cuisine favoured by the youth, the customers were spoilt for choice for their dining selections. The appealing smell of food wafted out of the restaurants into my nose. To stop tempting myself any further from eating as I already had my lunch, I continued my exploration around the mall.
