I’m really not to sure sorry about that

Step-by-step explanation:
Just add the like terms together.
Answer:
(a) Test statistic is -2.85 and p-value is 0.0022
(b) Reject the null hypothesis. The population mean of dissolved oxygen content is not equal to 10 mg/L
Step-by-step explanation:
H0: mu equals 10
Ha: mu not equals 10
The test is a two-tailed test because the alternate hypothesis is expressed using not equal to
(a) Test statistic (z) = (sample mean - population mean) ÷ (sd/√n) = (9.14 - 10) ÷ (2/√44) = -0.86 ÷ 0.302 = -2.85
Cumulative area of the test statistic = 0.9978
p-value = 2(1 - 0.9978) = 2(0.0022) = 0.0044
(b) The critical value using 0.02 significance level is 2.422. For a two-tailed test, the region of no rejection of the test statistic lies between -2.422 and 2.422.
Conclusion:
Reject the null hypothesis because the test statistic -2.85 falls outside the region bounded by the critical values -2.422 and 2.422.
The population mean of dissolved oxygen content is not equal to 10 mg/L
I would say 1 but I feel like that wouldn't help you and that's all I know, plus I don't want to look it up because of the policy. I wanna help tho, so that's all I'm gonna say (please don't get mad at me)
Answer:
Step-by-step explanation:
Annual gross salary = $28000
Income tax = 20% on anything above $15000
So she's taxable for $5000
Rent loan = $140 per month = $140 * 12= $1680 per annum
Tax deductible per annum = 20% of $5000
20 / 100 * $5000 = $1000
Total amount she takes home per annum =
Gross salary per annum - tax - loan =
($28000 - $1000 - $1680) = $25,320
Ayesha takes home $25,320 home annually.
