Probability of raining=0.45
Probability of not raining=1-0.45=0.55
The expected earning will be given by:
E(x)=240(0.55)+320(0.45)
E(x)=132+144
E(x)=276
Answer: $276

Step-by-step explanation:
Answer:
C.
normal distribution
Step-by-step explanation:
The Sampling Distribution of the Sample Proportion. If repeated random samples of a given size n are taken from a population of values for a categorical variable, where the proportion in the category of interest is p, then the mean of all sample proportions (p-hat) is the population proportion (p)
Sample proportion would be normal with mean = p and variance = pq/n where q = 1-p and n= the sample size
The condition is that both np and nq must be greater than 10
Hence we can take that this will be normal provided np>10 or p>1/4 and q >1/4
i.e. p lies between 1/4 and 3/4
C.
normal distribution (assuming conditions are satisfied)
