Answer:
90 packets
Step-by-step explanation:
Subtract the weight of the box.
33-1.5=31.5
There are 31.5kg of packets.
Convert it to g.
31500g
Divide it by the weight of one packet.
31500/350=90
The box holds 90 packets.

Answer:
The statistical conclusion is:
a) Your results are significant; one's willingness to wear masks is not independent of one's age.
Step-by-step explanation:
From this experiment,
The null hypothesis is established as:
H 0 = one's willingness to wear masks is independent of one's age.
The alternate hypothesis is established as:
H 1 = one's willingness to wear masks is not independent of one's age.
In statistics, if the absolute value of the test statistic is greater than the critical value, we declare statistical significance and reject the null hypothesis.
Since the test statistic = 16.5, which is higher than the critical value of 7.82, this establishes statistical significance. Thus, the null hypothesis is rejected.
Therefore, the statistical conclusion is that one's willingness to wear masks is not independent of one's age.
The answer is 5/6. What you do is take the 10 and the 12 and divide them by 2. You get 5/6,
