She harvested 93 kg of apples.
First you need to set it up like this:
X/75=24/100
Then you cross multiply and get:
1800=100x
The you isolate the variable (divide both sides) and get 18
75+18=93

Answer:a) z-value = -1.425 p-value= 0.077 statistically significant
Step-by-step explanation:
Given the following :
n1 = 100; x1 = 39 ; n2 = 100 ; x2 = 49
Z value for two independent samples can be obtained using the relation :
Z = (p1 - p2) /(√p(1-p)) * (√[(1/n1) + (1/n2)]
Z = -1.425
P-value : using the online p-value calculator at a confidence level of 90% from z score
Obtained p value = 0.077079
The p value is less than 0.1 , hence result is significant at p<0.10
