Step-by-step explanation:
- In Statistics,a two sample test is generally used to examine or compare two different population means with the main objective to verify whether the population means are equal or otherwise.
- The two sample t-test basically involves the hypothesis testing to determine or verify the equality between two concerned population means.
- In this case,the two different populations of raccoons are given and the equality of the mean sample weights of the two distinct populations can be determined or evaluated by employing the hypothesis testing method under a two sample t test for measuring difference in two population means.

Answer:
80 toy cars were left in the shop.
Step-by-step explanation:
Since there were toy cars, dolls and teddy bears in a shop, and 30% of the toys were toy cars, and the ratio of the number of dolls to the number of teddy bears were 4: 1, and there were 156 more dolls than toy cars, and after some toy cars were sold, 16% of the remaining toys in the shop were toy cars, to determine how many toy cars were left in the shop the following calculation must be performed:
Toy cars = 30%
Dolls and teddy bears = 70%
70/5 = 14 x 4 = 56
Dolls = 56%
Teddy bears = 14%
56 - 30 = 26
156/26 = 6 (1%)
Toy cars = 30 x 6 = 180
Dolls = 56 x 6 = 336
Teddy bears = 84
100 - 16 = 84
84 = 336 + 84 = 420
16 = X
84 = 420
16 = X
16 x 420/84 = X
80 = X
Therefore, 80 toy cars were left in the shop.
