Answer:
It would be less than 0.05.
Step-by-step explanation:
The hypothesis test was done to claim that the weight of participants has changed.
The null and alternative hypothesis could be written as:

being μ the population mean change in weight.
With that information, we can tell that is a two tailed test. Sample means that fall in any of the tails, with a z-statistic over 1.96 or under -1.96 (at a significance level of 0.05), will be evidence to reject the null hypothesis.
The information we have about the sample is the 95% confidence interval calculated from the sample information.
This confidence interval does not include the value μ=0.
Then, there is 2.5% of probabiltity that the population mean is under 2.177, the lower bound of the interval, which includes the value μ=0.
With this information, we can conclude that the P-value have to be under 0.05.
Answer:

Step-by-step explanation:
No. of red jelly = 10
No. of green jelly = 6
No. of yellow jelly = 7
No. of orange jelly = 5
Total number of jelly = 10 + 6 + 7 + 5 = 28

Hence, the required probability is 0.02 or 2 %
The answer is no. Not always.
There are times that the 4 digit number will involve carrying and it will be resulted into 5 digit number.
For example:
9 999 x 9, where 9 999 is a 4 digit number and 9 is a 1 digit number.
When you multiply this one, the answer will be 5 digit number.
9 999
x 9
=> 89 991, thus Joseph's statement does not apply to all multiplication process because not all 4 digit number multiplied with 1 digit number will result to 4 digit.
