represents the population mean .
Then, the set of hypothesis will be:-


We assume that this is normal distribution.
Sample size : n = 10, which is a small sample (n<30) ,s o we use t-test.
Sample mean : 
Standard deviation : 
The test statistic for population mean for small sample is given by :-


Hence , the value of test statistic = 1.460
26 because it’s a supplementary angle. d measures 52 degrees and 52/2 is 26.
Answer:
D
Step-by-step explanation:$400x.30=$120
400-120=280
$280x.10=28
280-28=252
